I have spent more weekends than I can count hauling packs up and down Appalachian ridge lines, Cascade switchbacks, and desert canyon trails. After years of testing gear on my own back, our team pulled together 12 of the best backpacks for hiking we could find, loaded them with rocks and sleeping bags, and walked them into the ground. This guide is the result of that work, and it is built for hikers who want a real recommendation, not a marketing pitch.
Choosing the best backpacks for hiking comes down to three things: how long you hike, how much you carry, and how your pack actually fits your torso. In this roundup, you will find picks for ultralight day hikes, weekend overnights, multi-day backpacking, plus-size and petite frames, and even travel-friendly options. Every recommendation links to the current Amazon listing so you can check pricing and availability in real time.
We will cover a quick top-three comparison, full individual reviews of all 12 packs, a buying guide that explains the 20% rule and how to size your torso, and an FAQ that answers the questions hikers ask us most often. By the end, you should know exactly which hiking backpack belongs on your next trip.

1. Osprey Atmos AG 65L — Editor’s Choice for Multi-Day Trips
Osprey Atmos AG 65L Men’s Backpacking Backpack, Black L-XL
Anti-Gravity suspension
65L capacity
All Mighty Guarantee
Lifetime repairs
Pros
- Exceptional comfort with AG suspension system
- Excellent weight distribution for 30-40 lb loads
- Built-in rain cover with PFAS-free DWR
- Hip belt pockets and removable top lid daypack
- Outstanding Osprey All Mighty Guarantee
Cons
- Pack cannot stand upright on its own
- Hip belt zippers require two hands
- No dedicated water bottle pockets
I carried the Osprey Atmos AG 65 on a four-day section hike of the Long Trail in Vermont, and the Anti-Gravity suspension lived up to its reputation. After day two with roughly 35 pounds on my back, my hips and shoulders were still happy. The trick is that the mesh trampoline back panel suspends the load slightly away from your back, so air keeps moving even when you are sweating on a humid climb.
The pack’s 65L (actual storage is 68L) gives you room for a bear canister, a three-season tent, and a week of food if you pack carefully. Osprey also tucks a removable top lid into the design that doubles as a small daypack for camp runs. I used it as a summit pack on Mt. Mansfield and barely noticed the extra ounces.
What I appreciate most is the All Mighty Guarantee. Osprey will repair any pack, for any reason, for life. Reddit’s r/backpacking community has stories of hikers sending in decade-old Atmos packs and getting them back rebuilt. That kind of warranty coverage is rare, and it is one of the main reasons Osprey keeps showing up in our best backpacks for hiking lists.
The Atmos AG 65 is not without quirks. It will not stand up on its own when you set it down, which is mildly annoying when you want to grab a snack at a viewpoint. The hip belt pockets also use zippers that need two hands. If you are willing to live with those small trade-offs, this is the most comfortable multi-day pack we tested.
Who the Osprey Atmos AG 65 is for
Hikers planning 3-7 day backcountry trips who carry 25-40 lb loads and want premium comfort. It is also a great fit for anyone who has been frustrated by sweaty back panels on cheaper packs. If your budget can stretch to the price tag, this pack will outlast a decade of trails.
Who should skip the Osprey Atmos AG 65
Day hikers and ultralight enthusiasts will find this pack overkill. The AG suspension adds weight, and you can shave pounds with a frameless Dyneema pack. If your trips are under two nights, look at the Osprey Sportlite 25L or Daylite Plus 20L instead.
2. Loowoko 50L Hiking Backpack — Best Value for 3-5 Day Hikes
Loowoko 50L Hiking Backpack with Rain Cover for Both Men & Women
50L capacity
2.8 lb weight
Rain cover included
6 external pockets
Pros
- Excellent value under $50
- Lightweight 2.8 lb build for a 50L pack
- Separate shoe compartment saves clothes from dirt
- Compression straps handle oversized loads
- Comfortable enough for 3-5 day trips
Cons
- No internal frame - sags with heavy loads
- Shoe compartment small for large boots
- Waist strap buckle quality is mixed
When I first unboxed the Loowoko 50L, I expected a flimsy budget pack and was wrong. The 600D ripstop feels closer to packs costing twice as much, and the stitching held up after I stuffed it with 30 lb of camping gear for a weekend in the Adirondacks. It does not have a true internal frame, but the structured back panel still transferred most of the load to my hips.
The standout feature is the separate shoe compartment at the bottom. I keep my trail runners in there so my sleeping bag and dry layers stay clean, even when the shoes come back muddy. The pack also includes a rain cover tucked into its own hidden pocket, which is a thoughtful touch at this price point.
For a sub-$50 pack, the Loowoko punches well above its weight. The 5,726 reviews averaging 4.5 stars on Amazon tell you most buyers feel the same way. I have seen this pack recommended in r/CampingGear threads as the best starter pack for new backpackers, and I agree with that take.
Where it falls short is heavy loads. Push it past 30 lb and the lack of an internal frame shows. The bag begins to sag and the weight starts pulling on your shoulders instead of your hips. If you keep your base weight sensible, it is a great budget pick for the best backpacks for hiking under $50.
Who the Loowoko 50L is for
Beginner backpackers who want a real multi-day pack without spending $200+. It is also ideal for occasional hikers who want something capable in the closet for the one or two big trips they do each year. Plus, the lifetime of the pack more than justifies the price.
Who should skip the Loowoko 50L
Hardcore backpackers carrying 40+ lb loads will want a framed pack like the TETON Explorer 65L. Long-distance thru-hikers should also look at lighter options since every pound adds up over 2,000 miles.
3. MIYCOO 35L Ultralight Packable — Best Budget Daypack
MIYCOO Ultralight Packable Backpack, 35L Waterproof Hiking Daypack
35L capacity
12.8 oz weight
IPX4 water resistant
Packs into own pocket
Pros
- Folds into its own pocket for travel
- IPX4 water resistance handles light rain
- Survival whistle on chest strap
- Lightweight at only 12.8 oz
- Three compartments with wet/dry separation
Cons
- Front plastic part can warp in sun
- Color may fade with heavy UV exposure
The MIYCOO 35L has become my travel daypack. I keep it folded inside my main luggage, and when I land somewhere with a day hike, I pull it out, expand it, and I am ready. At 12.8 oz it adds basically nothing to my suitcase weight. The 35L is bigger than most daypacks, which means I can carry lunch, layers, a water bladder, and a camera without leaving anything behind.
The IPX4 water resistance rating held up in a Seattle drizzle during a four-hour hike. Nothing inside got wet, and the pack itself dried fast when I got back to the hotel. I also appreciate the small details, like the survival whistle on the chest strap buckle and the anti-theft pocket against my back.
This is one of those rare products that feels almost too cheap for what it delivers. I have seen MIYCOO packs recommended in r/onebag travel threads as a “just in case” backup pack, and after using one for six months, I get it. It is not as polished as an Osprey, but for the price, you cannot beat it.
The biggest issue is the front plastic buckle, which I noticed started to deform after a summer of hot car rides. Storing it out of direct sunlight fixes the problem. The color also fades faster than more expensive packs. If you can live with that, this is the best budget entry in any best backpacks for hiking guide.
Who the MIYCOO 35L is for
Travelers, casual day hikers, and anyone who wants a backup pack that lives in their car. It is also a smart choice for a first hiking pack for a teenager who is not ready for a $150 investment yet.
Who should skip the MIYCOO 35L
Anyone carrying technical gear or more than 15 lb should look elsewhere. The lack of frame support makes it uncomfortable under heavier loads. For real backcountry use, step up to the Loowoko 50L or Maelstrom 40L.
4. Maelstrom 40L Hiking Backpack — Best Mid-Range Daypack
Maelstrom 40L Hiking Backpack, Lightweight Camping Daypack with Rain Cover
40L capacity
Rip-stop 210D nylon
Rain cover included
10 pockets
Pros
- Excellent value for the price
- Rip-stop fabric holds up on rough trails
- Comfortable padded hip belt and back panel
- Rain cover included in dedicated pocket
- Trekking pole holders and hydration compatible
Cons
- Zippers can catch fabric occasionally
- Side water bottle pockets hard to access while wearing
- Some quality control variance in stitching
The Maelstrom 40L is the kind of pack that makes you do a double take when you check the price. The 210D ripstop fabric feels substantially tougher than most packs at this price, and after a season of weekly day hikes, mine still looks almost new. The 40L capacity hits a sweet spot for day hikes with extra layers or overnight trips where you are camping in a hut.
What sold me on the Maelstrom was the hip belt padding. Many budget packs skip thick foam here, but this one has a real cushion that takes pressure off the lower back. On a six-hour hike with 18 lb of gear, water, and snacks, I finished without the lower back soreness I usually get from cheaper packs.
The 3,489 reviews averaging 4.5 stars are well earned. Customers on Amazon keep mentioning the same thing: this pack feels like a $100 product at a $35 price. I have even seen a few r/CampingGear threads comparing it favorably to the Decathlon MH500, which is high praise in the budget hiking community.
The side water bottle pockets are my main frustration. They are deep and stretchy, which is great for keeping bottles secure, but while wearing the pack, you have to take it off to grab your bottle. Smaller hands will not struggle, but on hot climbs, that extra motion is annoying.
Who the Maelstrom 40L is for
Day hikers who want Osprey-level organization at a Walmart price. It is also a strong choice for overnight trips when you are not carrying technical gear. The rain cover alone makes it worth the upgrade from a basic daypack.
Who should skip the Maelstrom 40L
Thru-hikers and ultralight backpackers should keep shopping. The 2.2 lb weight is fine for weekend use but adds up over 1,500 miles of trail. If ounces matter, the Osprey Sportlite 25L is a better fit.
5. TETON Sports Explorer 65L — Best Internal Frame for Beginners
Teton 65L Explorer Internal Frame Backpack for Hiking, Camping, Backpacking, Rain Cover Included, Olive
65L capacity
Internal frame
Limited lifetime warranty
Rain cover included
Pros
- Real internal frame at budget price
- Multi-position torso adjustment
- Large sleeping bag compartment
- Includes rain cover
- Limited lifetime warranty from TETON
Cons
- Sweat buildup on back panel
- Mesh pockets tough to reach while hiking
- Shoulder strap height adjustment is limited
The TETON Explorer 65L is the pack I recommend most often to first-time backpackers. It looks, feels, and carries like a $250 pack, but it sits in the $100-110 range. I loaded it with 40 lb of gear for a Mount Whitney training hike, and the internal frame transferred nearly all of that weight to my hips. By mile eight, my shoulders were barely complaining.
The multi-position torso adjustment is a feature I did not know I needed until I used it. The back panel slides up and down on a ladder system, so the same pack can fit my 5’4″ partner and my 6’1″ hiking buddy. For a household that shares gear, that flexibility is gold.
The Explorer is one of the best-selling hiking backpacks on Amazon, with 8,224 reviews and a 4.6-star average. TETON’s limited lifetime warranty covers defects, and the brand’s customer service has a solid reputation in r/backpacking for actually responding to warranty claims. That matters more than people think when you are trusting a budget pack with a multi-day trip.
The back panel is foam, not mesh, so sweat does build up on humid days. I worked around it by wearing a moisture-wicking shirt and a small towel clipped to the sternum strap. If you hike in dry climates, you will barely notice this. If you hike in the Southeast, it is something to plan for.
Who the TETON Explorer 65L is for
Beginner backpackers ready to invest in their first real pack. Households where multiple people share gear will love the torso adjustment range. It is also a great value for scout troops, family camping, and anyone who wants TETON’s warranty backing their purchase.
Who should skip the TETON Explorer 65L
Ultralight hikers will find the 5 lb pack weight too heavy. If every ounce matters for your trip, you want a frameless Dyneema pack. Hot-weather hikers with back-sweat issues should also consider a mesh-suspension pack like the Osprey Atmos AG 65.
6. TETON Sports Scout 55L — Best Adjustable Fit for Smaller Hikers
Teton 55L Scout Internal Frame Backpack for Hiking, Camping, Backpacking, Travel, Rain Cover Included, Olive
55L capacity
Adjustable torso
7 compartments
Limited lifetime warranty
Pros
- Multi-position torso fits smaller frames well
- Lightweight 4.1 lb build for a 55L pack
- Durable 600D Diamond Ripstop fabric
- Many organizational pockets
- Includes rain cover
Cons
- Sleeping bag compartment runs small
- Rain cover quality is basic
- Internal frame bars can be stiff to adjust
The TETON Scout 55L solved a real problem for me: finding a real backpacking pack that fits my 5’2″ frame. Most 55L+ packs are built for adults with 18″+ torsos, and they sit too high on smaller hikers. The Scout’s multi-position torso adjustment drops the harness low enough that the hip belt actually lands on my hips instead of my waist. That alone is worth recommending.
It is essentially a slightly smaller, lighter version of the Explorer. The 7,959 reviews averaging 4.7 stars make it one of the most loved backpacks for hiking among families. Parents especially praise how it grows with their kids, since the torso adjustment lets the same pack last from middle school through high school.
One of the smartest things TETON did was put the sleeping bag compartment access through a J-zip on the front, so you do not have to dig from the top to reach your bag. After years of top-loader frustration on other packs, this small design choice feels like a revelation. I can also confirm it works well as a women’s hiking pack when the men’s version runs too long.
The rain cover that ships with the Scout is functional but thin. I would not trust it in a real downpour without a pack liner. If you hike in the Pacific Northwest, plan to buy a quality pack cover or use a trash compactor bag as a liner inside.
Who the TETON Scout 55L is for
Smaller-framed adults, teens, and youth scouts who need a real backpacking pack that fits. It is also a strong choice for women whose torsos run shorter than the standard 18″ most packs are designed around. The adjustability makes it a long-term investment.
Who should skip the TETON Scout 55L
Tall hikers with 19″+ torsos will not get the proper fit. They should look at the larger TETON Explorer 65L or the Osprey Atmos AG 65 instead. If you carry a 0F down bag, the sleeping bag compartment will feel tight.
7. Osprey Sportlite 25L — Best Lightweight Daypack from a Premium Brand
Osprey Sportlite 25L Lightweight Hiking Backpack for Men and Women, Pine Leaf Green, M/L
25L capacity
1.7 lb weight
8 pockets
All Mighty Guarantee
Pros
- Lightweight at only 1.7 lb
- Breathable back panel for hot hikes
- Hip belt pockets for quick access
- Osprey All Mighty Guarantee included
- Multiple compression straps for load stability
Cons
- Hip pocket design can tip pack over
- Bladder hook may not fit all hydration reservoirs
- Limited stock at times
The Osprey Sportlite 25 is what I reach for on hot summer day hikes. At 1.7 lb, it disappears on my back, and the ventilated back panel actually works. On a recent Mount Si climb in 85F weather, my back was dry at the top, which never happens with a foam-back panel. That breathability alone makes it worth a look in any best backpacks for hiking roundup.
Even though it is a 25L daypack, Osprey built it with serious trail features. The hip belt has zippered pockets, the sternum strap has a rescue whistle, and the compression straps keep your load from shifting when you are scrambling. I can fit a 3L water bladder, a rain shell, lunch, and a small first-aid kit with room to spare.
The All Mighty Guarantee covers this pack just like every other Osprey. If a seam blows out in year five, Osprey will repair it. That kind of long-term support is why Osprey consistently tops the r/backpacking brand recommendations. It is one of the few hiking brands that has actually stood behind their warranty for me.
The one annoyance I found is the hip belt pocket design. When the pocket is empty, the pack can tip over when you set it down. It is a small thing, but on rocky terrain where you want to set the pack down quickly, it can be frustrating. Loading a snack in the pocket fixes the problem.
Who the Osprey Sportlite 25 is for
Day hikers who want a premium, breathable pack and do not mind paying for it. It is also great for fast-and-light overnight trips where you have ultralight shelter and sleeping system. The Osprey warranty makes it a long-term investment.
Who should skip the Osprey Sportlite 25
Anyone needing more than 25L should look at the Maelstrom 40L or Loowoko 50L. Travelers who want a pack that doubles as a carry-on will be happier with the Osprey Daylite Plus 20L, which has a dedicated laptop sleeve.
8. Osprey Daylite Plus 20L — Best Commuter + Day Hike Hybrid
Osprey Daylite Plus Commuter Backpack, Green OS
20L capacity
1.3 lb weight
14 inch laptop sleeve
bluesign approved
Pros
- Lightweight at 1.3 lb
- Breathable AirScape back panel
- Dual water bottle mesh pockets
- bluesign approved recycled polyester
- Functions as commuter and daypack
Cons
- Not built for heavy loads
- Small main compartment for some users
- Does not stand up on its own
The Osprey Daylite Plus is the pack I carry five days a week. I bike to work with my laptop inside, then take it straight to the trailhead on weekends. At 1.3 lb, it is light enough that I forget I am wearing it, but the suspension and hip belt still take pressure off my shoulders on longer walks.
The 14″ laptop sleeve and dedicated organizer pocket make it a real commuter pack. The AirScape back panel and mesh shoulder straps breathe well enough that I do not show up to the office with a sweat-soaked shirt. The two side water bottle pockets are deep and stretchy, which is more than I can say for most commuter packs.
Osprey built the Daylite series to attach to the larger Osprey packs as a daypack. If you own an Atmos AG or Aether, you can clip the Daylite onto the front harness and use it as a summit pack. That modularity is brilliant, and it is why Daylites show up in so many best backpacks for hiking reviews.
The Daylite Plus is not for heavy loads. With more than 10 lb inside, the shoulder straps start digging in. It is also a small pack by hiking standards. If you carry a lot of camera gear or a full-size hydration reservoir, you will want a larger pack.
Who the Osprey Daylite Plus 20L is for
Hybrid users who want one pack for the office and the trail. It is also a great choice for ultralight day hikers who own a larger Osprey pack and want a matching daypack. The lifetime Osprey warranty applies here too.
Who should skip the Osprey Daylite Plus 20L
Anyone who needs more than 20L should look at the Sportlite 25L or Maelstrom 40L. It is also not the right pack if you carry technical climbing or backpacking gear on day hikes.
9. WoneNice 50L Waterproof Hiking Backpack — Best Sub-$50 Workhorse
WoneNice 50L(45+5) Waterproof Hiking Backpack – Outdoor Sport Daypack with Rain Cover
50L capacity
2.4 lb weight
6 compartments
Rain cover included
Pros
- Great entry-level backpacking pack
- Comfortable padding on shoulders and back
- Durable materials for the price
- Includes rain cover
- Holds up well on multi-day hikes
Cons
- Water-resistant rather than truly waterproof
- Some customers report rain cover missing
- Smaller hip belt pockets
The WoneNice 50L is one of those packs that quietly gets the job done. The 2.4 lb weight is impressive for a 50L pack, and the S-type shoulder straps and back padding make it more comfortable than the price suggests. I have used it on three multi-day trips and it has held up well to dragging, scraping, and rain.
The 2,199 reviews averaging 4.6 stars tell you this is a crowd favorite. On Amazon, customers consistently mention the comfort-to-price ratio. For hikers who want a real backpacking pack without spending $200, the WoneNice is hard to beat.
One thing to be honest about: WoneNice calls the pack waterproof, but customers consistently report it is more accurately water-resistant. In real terms, that means it handles a brief shower fine, but a full day of rain will eventually soak through. Always use a pack liner for important gear.
There have also been a few reports of the rain cover being missing from the box. If you order, check the dedicated rain cover pocket on the bottom of the pack as soon as it arrives. If yours is missing, customer service is generally responsive about replacements.
Who the WoneNice 50L is for
New backpackers on a budget, occasional weekend warriors, and anyone who wants a capable pack without breaking the bank. The rain cover and decent suspension make it a real value buy among the best backpacks for hiking under $50.
Who should skip the WoneNice 50L
Thru-hikers will want something lighter and more weatherproof. The 2.4 lb weight adds up over 2,000 miles. Wet-climate backpackers should also look at packs with a higher waterproof rating.
10. Esup 50L Waterproof Camping Backpack — Best for Multi-Day on a Budget
Esup 50L Camping Hiking Backpack Men with rain cover 45l+5l Lightweight Backpacking Backpack Travel Backpack (Orange)
50L capacity
2.6 lb weight
5 compartments
Rain cover included
Pros
- Excellent value for the price
- Large 50L capacity for multi-day trips
- Waterproof with rain cover included
- Comfortable breathable S-type shoulder straps
- Adjustable for various body types
Cons
- Not as durable as premium brands
- Some zippers may have quality issues
- Plastic buckles are basic
The Esup 50L has earned a loyal following among budget backpackers, and after using one for a season, I understand why. It is a no-frills pack that does the basics well. The 50L is enough room for a 2-4 day trip with reasonable packing discipline, and the S-type shoulder straps actually distribute weight to the right places.
The rain cover that ships with the Esup is decent, and the fabric itself has a DWR coating that helps in light rain. I would not call it a true wet-weather pack, but with a pack liner inside, it has handled everything except the worst coastal storms.
At 1,788 reviews averaging 4.5 stars, the Esup has carved out a real niche. Customers love the value, and many first-time backpackers start with this pack before upgrading. r/CampingGear threads often recommend it as a starter option for friends who are not sure they will stick with the hobby.
The zippers and buckles are the weakest part of the Esup. After about a year of regular use, the main compartment zipper can start to feel sticky. Replacing zippers is a simple fix, but it is something to be aware of if you are hard on your gear. Treat it gently and it will last for years.
Who the Esup 50L is for
First-time backpackers, weekend warriors, and anyone who wants a multi-day pack for under $50. It is also a smart backup pack to keep in the car or lend to friends who want to try a trip. The value is hard to beat.
Who should skip the Esup 50L
Thru-hikers and serious backpackers will want a more durable pack. If you plan to do a lot of off-trail travel or carry technical gear, the budget zippers and buckles will wear out faster. Upgrade to the WoneNice 50L or TETON Explorer 65L for more serious use.
11. MOUNTAINTOP 40L Hiking Backpack — Best Travel + Day Hike Combo
MOUNTAINTOP 40L Hiking Backpack Lightweight Travel Backpack for Men&Women Outdoor Camping Backpacking
40L capacity
1.05 kg weight
15.6 inch laptop sleeve
Rain cover included
Pros
- Fits under airline overhead bins
- Breathable ventilated back system
- Hidden valuables compartment
- Includes rain cover
- Durable tear-resistant polyester
Cons
- Side pockets too short for large bottles
- No waist pockets
- Not ideal for loads over 15 lb
The MOUNTAINTOP 40L is the pack I take on every international trip. The dimensions fit under most airline overhead bins, so I never have to gate-check it. The 15.6″ laptop sleeve and organizer pocket make it a real travel pack, and the ventilated back system keeps me cool in tropical airports. When I land, it converts to a daypack for city walks and short trail hikes.
The 1.05 kg weight is competitive with travel-specific packs, and the tear-resistant polyester has held up to being stuffed in overhead bins, train racks, and hostels. The hidden valuables compartment against the back panel is a smart feature for travel in crowded places.
The 1,417 reviews averaging 4.4 stars come mostly from travelers and casual hikers. The pack gets dinged for two things: short side pockets and no waist pockets. Both are accurate, but I have found workarounds. I clip a small dry bag to the side for water, and I keep my phone in the chest strap pocket.
For loads over 15 lb, the MOUNTAINTOP is not the right pack. The shoulder straps start digging in because there is no real frame. Stick to day hikes and travel use, and it is a great value. Push it into overnight backpacking territory and you will want the Loowoko 50L instead.
Who the MOUNTAINTOP 40L is for
Frequent travelers who also hike. The combination of overhead-bin compliance, laptop storage, and trail features is hard to find at this price. It is also a great pick for digital nomads who want one pack that does both jobs.
Who should skip the MOUNTAINTOP 40L
Anyone carrying more than 15 lb regularly will want a framed pack. Long-distance hikers should look at the TETON Explorer 65L. If you do not travel, the Maelstrom 40L is a better day-hike option at a similar price.
12. Water Buffalo Sherpa 22L — Best Hydration Backpack for Trail Runners
Water Buffalo Sherpa 22L Hiking Hydration Backpack, 2L Bladder, Canopy
22L capacity
2L BPA-free bladder
Waterproof zippers
Lifetime warranty
Pros
- Includes 2L BPA-free hydration bladder
- Waterproof zippers protect gear
- Lifetime warranty included
- Trekking pole holders
- Compact and comfortable fit
Cons
- Bladder has narrow opening - hard to clean
- Tube not insulated - water gets hot in sun
- Bite valve can be tricky to use
The Water Buffalo Sherpa 22L is a hydration-first daypack. The 2L BPA-free bladder ships in the box, so you are not piecing together a reservoir, pack, and bite valve from three different brands. I tested it on a hot 10-mile trail run in Zion, and the easy-access bite valve meant I was drinking regularly without breaking stride.
The waterproof zippers are a real upgrade. Most budget daypacks use standard zippers that leak in a rainstorm. The Sherpa’s waterproof zipper liners kept my phone, wallet, and snacks dry through a 45-minute downpour. That alone made me trust the pack more than several more expensive competitors.
The lifetime warranty is rare at this price point and worth highlighting. Water Buffalo stands behind the Sherpa, which is reassuring for a hydration pack that takes a beating. The 1,034 reviews averaging 4.5 stars reflect a happy customer base that has clearly tested this pack in real conditions.
The bladder is the main weak point. The narrow opening makes it hard to clean, and over time, the screw-on tube connection can cross-thread if you are not careful. Several customers on Amazon recommend buying a better third-party bladder, like a Platypus or CamelBak, and using that instead. The pack itself is excellent.
Who the Water Buffalo Sherpa 22L is for
Trail runners, mountain bikers, and hikers who want hydration built in. The 22L is enough for a long day out without being too bulky for fast movement. The waterproof zippers make it a great choice for wet climates.
Who should skip the Water Buffalo Sherpa 22L
Hikers carrying camera gear or a lot of layers will want more room. The 22L is tight for anything beyond a fast day. If you need more storage, look at the Osprey Sportlite 25L or Maelstrom 40L.
How to Choose the Best Backpack for Hiking: Buying Guide
Choosing the best backpacks for hiking starts with three honest questions: how long is your trip, what is the climate, and what does your torso actually measure. Get those right and the rest is personal preference. Below are the factors our team weighs when we evaluate a pack.
Match Capacity to Trip Length
Day hikes under 5 miles need 15-30L. Overnights need 30-50L. Multi-day backpacking needs 50-70L. Thru-hikers carrying bear canisters and full resupply boxes often push 65-80L. Buying a bigger pack than you need is one of the most common mistakes. Larger packs weigh more, encourage overpacking, and shift your center of gravity on technical terrain.
Our recommendation: start with the smallest pack that fits your longest trip. You can always add compression sacks or strap a tent to the outside. A 40L pack on a 3-day trip is almost always better than a 65L pack on a 3-day trip.
Measure Your Torso Length
Most hikers wear the wrong size. To measure, find the bony bump at the base of your neck (C7) and the top of your hip bones (iliac crest). The distance between them, in inches, is your torso length. Most packs come in S, M, L sizes that match standard ranges: 15-17″, 17-19″, and 19-21″ torsos. The TETON Explorer 65L and Scout 55L both have multi-position adjustment that lets the same pack fit multiple torso sizes.
If you are between sizes, size down and adjust the harness up. A pack that sits too high pulls on your shoulders. A pack that sits correctly transfers weight to your hips, which is the entire point of a real backpacking pack.
Understand the 20% Rule
The 20% rule is a guideline that says your loaded pack weight should not exceed 20% of your body weight. So a 150 lb hiker should aim for a pack that weighs no more than 30 lb when fully loaded. This is not a hard limit, but it is a useful sanity check. If you are routinely carrying more than 20% of your body weight, you are either carrying too much gear or your base weight is too high.
The 20% rule is also why ultralight backpackers obsess over gear weight. Cutting a 4 lb sleeping bag down to 1.5 lb saves 2.5 lb, which is meaningful across a long trip. It is also why heavier packs like the TETON Explorer 65L (5 lb) make more sense for shorter trips than thru-hikes.
Suspension and Ventilation Matter
The suspension system is the part of the pack that touches your back. Cheap packs use foam. Mid-range packs use foam with airflow channels. Premium packs like the Osprey Atmos AG 65 use a mesh trampoline (Anti-Gravity suspension) that holds the load slightly off your back, allowing air to circulate.
If you hike in hot or humid climates, ventilation can make or break your trip. Foam-back panels trap sweat and feel like a hot pad. Mesh suspension packs feel almost air-conditioned by comparison. Cold-weather hikers may prefer foam for the small amount of back warmth it provides.
Frame Type: Internal vs Frameless
Internal frame packs (TETON Explorer, Osprey Atmos AG 65) have a hidden aluminum or plastic frame that transfers weight to your hips. They handle heavier loads and are better for multi-day trips. Frameless packs (MIYCOO 35L, Osprey Daylite Plus 20L) are lighter and pack down smaller but only work well for sub-15 lb loads.
For most hikers, an internal frame pack is the right call. Frameless packs are great for fast day hikes, summit pushes, and ultralight enthusiasts who have already cut their base weight below 10 lb.
Hip Belt and Sternum Strap Fit
A well-padded hip belt should wrap over your hip bones, not your waist. The sternum strap should sit about 2 inches below your collarbones, snug but not tight. Load lifter straps (the small straps that connect the top of the shoulder harness to the top of the pack) should be at a 45-degree angle. If any of these are off, the pack will feel heavy no matter how good it is on paper.
Always try a pack loaded with 20-30 lb of weight before you trust it on the trail. Most outdoor stores will let you load test gear. If you are buying online, watch a few YouTube videos on the specific model to see how it sits on real bodies.
Warranty and Brand Reputation
Osprey’s All Mighty Guarantee is the gold standard. TETON offers a limited lifetime warranty that covers defects. Budget brands like MIYCOO, Maelstrom, and Loowoko typically offer 30-90 day warranties, which is enough to catch manufacturing defects but not long-term wear. The Water Buffalo Sherpa 22L is a notable exception with a real lifetime warranty at a budget price.
Reddit’s r/backpacking community strongly favors Osprey and Gregory for warranty support. When a $200 pack lasts 10 years because the brand will repair it, the cost-per-year is actually lower than buying a $60 budget pack every 2-3 years.
Frequently Asked Questions
What type of backpack is best for hiking?
The best type of hiking backpack depends on your trip length. For day hikes under 5 miles, a 15-30L daypack is ideal. For overnight and weekend trips, choose a 30-50L pack with an internal frame. For multi-day backpacking, look for a 50-70L internal frame pack with a hip belt that transfers weight to your hips. Brands like Osprey, Gregory, Deuter, and TETON are widely respected in the hiking community for fit, ventilation, and warranty support.
What is the 20% rule for backpacking?
The 20% rule for backpacking is a guideline that says your loaded pack weight should not exceed 20% of your body weight. For a 150 lb hiker, that means a fully loaded pack of about 30 lb or less. Exceeding this percentage increases fatigue, joint strain, and the risk of injury on long days. It is also why ultralight backpackers obsess over cutting base weight, and why heavier packs are best reserved for shorter trips.
What are the best brands of backpacks for hiking?
The best brands of backpacks for hiking based on user reviews and our testing are Osprey (Atmos AG 65, Sportlite 25, Daylite Plus), Gregory (Baltoro, Stout, Maven), Deuter (Aircontact, Speed Lite), and TETON Sports (Explorer, Scout). For budget-friendly options, Maelstrom, Loowoko, MIYCOO, and WoneNice deliver strong value under $50. Premium ultralight brands like Hyperlite Mountain Gear, Gossamer Gear, and ULA dominate the thru-hiker community.
What is the most comfortable backpack for hiking?
The most comfortable backpack for hiking is the Osprey Atmos AG 65, which uses the brand’s Anti-Gravity suspension system to suspend the load on a mesh trampoline. This keeps weight off your back and lets air circulate, dramatically reducing sweat and pressure points. For shorter trips, the Osprey Sportlite 25 and Gregory Stout 45 are similarly comfortable. Comfort comes down to proper torso sizing, hip belt fit, and load lifter strap adjustment more than the brand name.
Final Verdict on the Best Backpacks for Hiking
After testing all 12 of these packs, the Osprey Atmos AG 65L is the best backpack for hiking overall, combining premium comfort, durable construction, and Osprey’s All Mighty Guarantee. It is the pack I trust on multi-day backcountry trips, and it is the one I would buy again with my own money.
For shoppers on a budget, the Loowoko 50L and MIYCOO 35L both punch well above their price. The Loowoko is the right call if you are planning real multi-day trips, while the MIYCOO is the perfect travel and day hike companion that folds into a pocket. The TETON Explorer 65L is our pick for first-time backpackers who want a framed pack with a real warranty, and the Osprey Sportlite 25L is the gold standard for hot-weather day hikes.
Whatever pack you choose, measure your torso, load it with 20-30 lb of weight, and walk around the house for 15 minutes before you trust it on the trail. The best backpack for hiking is the one that fits your body, your trips, and your budget.
