Our quick picks

What follows is the reasoning, the specifications that change the decision, and the drawbacks.

Your height has almost nothing to do with which backpack fits you. Torso length does, and it varies enormously between people of the same height — a six-foot-two person with long legs can have a shorter torso than a five-foot-eight person with a long back. Buying a pack by your height is the single most common reason a pack that looked right in the box hurts after three miles.

Measuring it takes two minutes and one other person. Find the bony bump at the base of your neck where your shoulders meet — the C7 vertebra, easiest to locate if you tip your head forward. Then put your hands on your hips with thumbs pointing backwards and find the shelf of your pelvis, the iliac crest. Have someone measure the distance between those two points along your spine. That number, in inches, is what pack sizes are built around: roughly under 16 is extra small, 16 to 18 small, 18 to 20 medium, and over 20 large. Many packs are adjustable across a range, which is what makes them forgiving.

The second thing that changes everything: the hip belt carries the load, not the shoulders. A correctly fitted pack transfers most of the weight — commonly quoted at around 80% — through the belt onto your pelvis, which is built to carry it. The shoulder straps only stabilise. So the belt must sit wrapping the iliac crest, not around your waist above it, and if your shoulders ache at the end of a day the cause is almost always a belt sitting in the wrong place or a torso length that does not match.

Below are six packs from day hikes to multi-day trips, plus a section on load weight and fitting. If you are building out a kit, our guides to the best camping tents and the best sleeping bags cover what goes inside.

Quick picks

• Best overall: Osprey Atmos AG 65 — the Anti-Gravity suspension is the most comfortable load carry in the category, with a PFAS-free raincover included.
• Best value multi-day pack: Teton 65L Scout — multi-position torso adjustment and a feature set that punches far above its price.
• Best budget large pack: Naturehike 65L Rock — 65 liters of capacity and an internal frame for a fraction of premium money.
• Best for overnights and long day hikes: Maelstrom 40L — the size most people actually need, light and well padded.
• Best day pack: Gregory Arrio 24L — a suspended mesh backpanel that keeps your back cool, which is the thing you notice on a hot climb.
• Best do-everything pack: Kelty Asher — sized to work as a big daypack or a light overnight pack, with a tailored fit system.

Read this first: fitting a pack and how much to carry

A pack that does not fit causes back, shoulder and knee pain, and a pack that is too heavy is one of the commonest reasons walkers get into trouble on descents. None of this is medical advice — if you have a back, hip or knee condition, or you are recovering from an injury, that is a conversation with a doctor or a physiotherapist before you load twenty-five pounds onto your spine.

How to fit it, in order

Do this with weight in the pack, not empty. A pack that feels fine empty can be unbearable with thirty pounds in it, which is why trying it loaded is the only meaningful test.

• 1. Loosen everything, then put the pack on and do up the hip belt first.
• 2. Position the hip belt on the iliac crest, so the padding wraps the bony shelf of your pelvis with the center of the padding over the crest. Not on your waist, not on your hips below the bone. Tighten it firmly — firmer than feels natural at first.
• 3. Tighten the shoulder straps until they follow the contour of your shoulders and the harness wraps without gaps, but not so tight that they take the weight off the belt. You should be able to slide a finger under them.
• 4. Set the load lifters. These are the small straps running from the top of the shoulder harness up to the frame. They should leave the harness at roughly a 45-degree angle. If they are flat or pointing down, the torso length is too long; if they are steeply vertical, it is too short. This is the single best diagnostic that you have the right size.
• 5. Fasten and adjust the sternum strap across your chest, below the collarbones, snug but not restricting breathing.
• 6. Fine-tune the stabiliser straps at the sides of the hip belt to pull the load in toward your back.
• 7. Walk around for at least ten minutes, loaded, including up and down stairs. Discomfort shows up on descents first.

How much weight is reasonable

• A common guideline is no more than about 20% of your body weight for a fit adult on a multi-day hike, with 25% as an upper limit rather than a target. For day hikes, 10% is plenty.
• Children and teenagers should carry considerably less — frequently quoted at 10 to 15% of body weight — in a youth-specific pack with an adjustable torso, because they are still growing.
• Build up gradually. Carrying a heavy pack is a physical activity in its own right, and going from nothing to a loaded multi-day pack is how people injure themselves. Practice with weight before the trip.
• Weight is the main cause of descent injuries. Going downhill with a heavy pack multiplies the load through your knees and ankles, and tired legs plus a high pack is how people turn an ankle in a place that is awkward to be rescued from. Trekking poles help considerably.
• Reduce weight before you buy a bigger pack. The usual sequence is that people buy a larger pack, fill it, and then wonder why hiking hurts. Weigh what you are carrying and take things out.

Packing so the load sits right

• Heavy items centered, close to your spine, at mid-back height. Water, food and cooking kit go there. Weight held away from your back or too high makes you unstable on uneven ground.
• Sleeping bag at the bottom, where it acts as a cushion and fills the space the hip belt wraps around.
• Light and bulky at the top — spare clothing, a jacket.
• Things you need during the day in the lid, the hip belt pockets and the side pockets: map, snacks, water, waterproof, first aid. A pack you have to unpack to find your rain jacket is a pack you get wet in.
• Nothing loose swinging outside. Items strapped on badly catch on branches and shift the balance.
• Rain covers do not keep a pack dry. Water runs down your back inside the cover, and seams and zips leak. Use a pack liner as well — a dry bag or even a heavy-duty trash bag inside the main compartment — and pack your sleeping bag and spare clothes in their own dry bag. This is cheaper and more reliable than any cover.

Women’s-specific packs are a real difference

Not marketing. Women’s-specific packs generally have a shorter torso range, narrower and more curved shoulder straps to clear the chest, and a hip belt shaped and angled for a different pelvis. For many women a women’s pack in the right torso size is dramatically more comfortable than a unisex one, and for some the unisex fit is fine. Try both if you can. The same applies in reverse: some men fit women’s packs better, and nothing bad happens if you buy one.

What we looked at

We built this list from current Amazon listings, manufacturer specifications and the recurring patterns in verified buyer feedback. We have not carried all six of these on a week-long trip, and we are not going to imply we ran comparative load tests. What we did was assess each on the things that determine whether a pack works: whether the torso length is adjustable and over what range, hip belt construction, frame and suspension design, how the pockets are laid out, and whether the volume is honest.

We weighted heavily toward feedback that mentions specific loads and distances, because “comfortable pack” from someone who used it as carry-on luggage tells you nothing. We weighted heavily against recurring reports of hip belts that will not hold tension, zips failing under load, and stated volumes that do not match reality.

Every pick holds a customer rating of 4.4 stars or better. One note: we excluded a well-regarded lightweight pack from a specialist brand because its listing carried too little published detail to describe honestly, which is a recurring problem with enthusiast gear on marketplaces. If you are shopping for an ultralight pack specifically, a specialist retailer with full specifications is a better route than a marketplace listing.

What to know before you buy

Volume: almost everyone buys too big

A pack gets filled to its capacity. That is not a joke about willpower — it is that empty space gets used, and a 75-liter pack on a weekend trip ends up carrying 75 liters of things you did not need. Buying the smallest pack that fits your actual kit is the most effective weight-saving decision available.

• 15 to 25 liters: day hikes. Water, food, layers, first aid, a map. This is what most people need most of the time.
• 25 to 40 liters: long day hikes, winter day hikes with extra layers, fastpacking, and an ultralight overnight if you are experienced.
• 40 to 50 liters: one or two nights for most people, or several nights if your kit is light and modern.
• 50 to 65 liters: the multi-day sweet spot. Three to five nights with normal gear, and the range most backpacking packs sit in for good reason.
• 65 to 75 liters and above: winter trips with bulky insulation, expeditions, carrying a share of a family’s or a group’s kit, or photography gear. Not a beginner’s first pack.
• Check whether the stated volume includes the pockets. Some manufacturers quote main compartment only and some quote everything, which makes comparisons between brands unreliable.

Frame types, and what they suit

• Internal frame is what nearly every pack here uses: a frame sheet, stays or a perimeter frame inside the pack that transfers load to the hip belt. It carries heavy loads well, hugs the body, and is the right choice for almost everyone.
• Frameless packs save a couple of pounds and rely on carefully packed contents to give structure. They are excellent under about twenty pounds and unpleasant above it. Ultralight hikers use them; first-time backpackers should not.
• External frame packs are now rare. They ventilate well, carry awkward heavy objects and are cheap secondhand, and they are less stable on rough ground. Worth knowing they exist, not worth seeking out unless you are hauling odd loads.
• Suspended mesh backpanels — a tensioned mesh sheet holding the pack slightly off your back — are much cooler and hold the load a little further from your spine. Excellent in heat, a small compromise in stability with very heavy loads.

The details you will notice on the trail

• Hip belt pockets. Somewhere to put snacks, a phone and lip balm that you can reach without stopping. Their absence is the omission people complain about most.
• Side water bottle pockets you can actually reach while wearing the pack. Many are placed so you cannot, which means stopping every time you drink, which means drinking less.
• Top lid versus panel access. A top-loading pack is stronger and lighter; a panel or side zip lets you reach the middle without unpacking. A zip is also a failure point under load.
• Sleeping bag compartment. A separate bottom section with a divider. Useful if you like the separation, dead weight if you prefer one big space — most have a removable divider so you can choose.
• Trekking pole and ice axe attachments if you use them. Stowing poles on the pack while scrambling is useful.
• Hydration sleeve and port for a reservoir, which is the easiest way to drink enough.
• Pack weight itself. A heavy, feature-rich pack can weigh five or six pounds empty. That is five or six pounds of your weight budget spent before you pack anything.
• Fabric denier. Higher denier means tougher and heavier. For trail use, mid-range is the sensible compromise; ultralight fabrics are lighter and less abrasion-resistant against rock.

The 6 best hiking backpacks

1. Osprey Atmos AG 65 — best overall

The Anti-Gravity suspension is the reason this pack has been the reference point for multi-day comfort for years. Rather than a flat backpanel with padding, a continuous mesh wraps from the back through to the hip belt, so the load presses evenly across a large area instead of on a few contact points. The practical effect is that a loaded pack feels like it is hugging you rather than sitting on you, and that difference shows up at hour six rather than in the shop.

It is also a thoroughly finished pack. The included raincover uses a PFAS-free water repellent treatment, which matters because the traditional chemistry is the part of outdoor gear under the most environmental scrutiny. There is curved zip access on one side of the panel so you can reach the middle of the pack without unpacking from the top, and a floating top lid with lash points for the things that do not fit inside. Customer rating is 4.7 stars.

Why it made the list: for multi-day loads it is the most comfortable pack most people will ever wear, and comfort is the whole point of a backpack. The PFAS-free raincover and the panel access are the kind of details that show a pack has been revised over many generations rather than designed once.

The drawbacks: it is expensive, and a substantial part of that is the suspension system — if you are carrying light loads on short trips you will not collect the benefit. It is also heavier than a simple pack, because the suspension is structure, and that weight comes out of your carrying budget. Sixty-five liters is more pack than many people need; be honest about your kit before choosing this size. Osprey sells it in torso size ranges, so measure your torso and order the right one rather than assuming. And a suspended mesh back holds the load slightly further from your spine, which is cooler and marginally less stable on scrambling terrain.

Who it is for: multi-day backpackers, anyone carrying over about thirty pounds, hot climates, and anyone who has been uncomfortable in a cheaper pack and wants to know what the difference is.

2. Teton 65L Scout — best value multi-day pack

Teton’s whole proposition is giving you the specification of a much more expensive pack and accepting more weight in exchange, and in packs that trade works better than in most categories — because the feature that matters most is fit, and fit does not have to be expensive. The Scout has multi-position torso adjustment, which is the single most important thing in this guide: it means you can set the pack to your measured torso length rather than hoping your height corresponds to a size.

It is an internal frame pack with a full complement of pockets, compression straps and attachment points at a price that makes buying a first backpacking pack a low-risk decision. Customer rating is 4.7 stars across a very large review base, and Teton has been selling this line long enough for the feedback to be meaningful rather than early enthusiasm.

Why it made the list: it is the pack to buy for a first multi-day trip, or for someone who is not yet sure they will do enough backpacking to justify a premium pack. Adjustable torso length means it can be fitted properly, which is most of what makes a pack comfortable, and if you take up backpacking seriously you will have learned what you want from the next one.

The catch: it is heavier than premium packs of the same volume, and that empty weight comes out of your load budget — on a light trip a heavier pack can mean carrying more total weight than with a lighter, pricier one. The suspension is functional rather than sophisticated, so above roughly thirty-five pounds you will feel the difference against the Osprey. Materials and hardware are good for the price and not premium. And check the exact model, because Teton’s Scout and Explorer lines are similarly specified and priced with different features.

Who it is for: first backpacking packs, scouts and youth groups, occasional multi-day hikers, and anyone who wants a properly fitted pack without premium spending.

See the Teton 65L Scout on Amazon →

3. Naturehike 65L Rock — best budget large pack

This is the pick for maximum capacity at minimum cost, and it is a more serious pack than its price implies. Naturehike quotes a 60-plus-5-liter capacity from an extendable collar, an internal frame, and a fabric with high-molecular-weight polymer content in the weave — which in practical terms means better tear resistance for the weight than plain nylon.

Naturehike is a Chinese outdoor brand that has built a genuine following among budget-conscious hikers by making equipment that works without the marketing overhead of the established names. Customer rating is 4.4 stars.

Why it made the list: there is a real case for a large cheap pack. Someone carrying a share of a family’s gear, a student on a long trip, or anyone who needs the volume once a year and does not want to spend like a thru-hiker is well served by this, and it meets the basic requirement of having an internal frame and a hip belt that transfers load.

Where it falls short: torso adjustment range is narrower than the Teton’s, so check the stated fit against your measured torso before ordering — a large pack that does not fit is worse than a small one that does. The suspension is basic, so heavy loads will be less comfortable than on either pack above. Hardware and zips are the components most likely to be the limit on its life. Support and warranty from a brand with a smaller US presence is less certain. And as with all 65-liter packs, the volume is an invitation to overpack.

Who it is for: tight budgets, occasional large-volume needs, carrying a share of group gear, students and travelers.

4. Maelstrom 40L — best for overnights and long day hikes

Forty liters is the size most people should own and the size fewest people buy. It is enough for a long winter day hike with spare layers, enough for an overnight with modern lightweight kit, and enough for a weekend if you are disciplined — and it is small enough that you cannot fill it with things you do not need, which is the real benefit.

The Maelstrom is a well-padded, lightweight pack in that size, with a thicker padded back panel than most packs at its price and a sensible multi-compartment layout. Customer rating is 4.5 stars.

Why it made the list: it fills the gap between a daypack that is too small for a big day out and a backpacking pack that is more than you need. For most people’s actual hiking — long days, the occasional overnight, travel — this is the correct volume, and choosing it instead of a 65-liter pack will save you weight every single time you use it.

What owners complain about: at 40 liters it will not carry a bulky winter sleeping bag and a tent together comfortably; if a multi-day trip is the plan, this is the wrong pack. Torso adjustment is limited compared with a dedicated backpacking pack, so check the fit. The frame and suspension are lighter, which is fine at twenty-five pounds and unpleasant at thirty-five. Maelstrom is a less established name, so long-term durability is less proven. And the padding that makes it comfortable also makes it warmer against the back than a suspended mesh design.

Who it is for: long day hikes, winter day hikes, lightweight overnights, travel, and anyone who currently owns a 20-liter daypack and a 65-liter monster and nothing in between.

5. Gregory Arrio 24L — best day pack

Most hiking is day hiking, and the thing you notice on a day hike in summer is not the weight — it is the sweat patch. Gregory’s FreeSpan backpanel suspends the pack on an open-air mesh sheet, so air moves between the pack and your back instead of the pack sitting against a wet shirt. On a long climb in heat that is the difference between comfortable and miserable.

It is a straightforward top-loading pack with a drawstring closure, a perforated breathable shoulder harness, and the 24-liter volume that suits a full day out with water, food, layers and a first aid kit. Gregory has been making packs since the 1970s and its fit and suspension work is why professionals use the brand. Customer rating is 4.4 stars.

Why it made the list: it is the right pack for the hiking most people actually do, and it prioritizes the thing that matters on a day hike rather than the things that matter on a week-long one. A cool back is an underrated feature and the reason people reach for one pack over another in July.

The downside: it is one size fits all, which means no torso adjustment — at 24 liters and light loads that matters far less than on a backpacking pack, but if you are at either extreme of torso length, try it before committing. Top-loading with a drawstring means reaching things at the bottom involves emptying it; that is the trade for light weight and strength. Twenty-four liters is a day pack and not an overnight pack, whatever you read on a forum. And a suspended mesh panel is slightly bulkier against the back than a flat panel, so it sits a little further out.

Who it is for: day hikers, hot climates, anyone who sweats on climbs, and anyone who wants one good pack for the walking they actually do.

6. Kelty Asher — best do-everything pack

Kelty designed the Asher to straddle the line between a large daypack and a light overnight pack, which is the most useful place a single pack can sit if you are only going to own one. It is hydration compatible, has a tailored fit system rather than a single fixed size, and carries the specification of a more expensive pack at an entry price — which is more or less Kelty’s founding proposition as a company.

Kelty has been making American outdoor equipment since the 1950s and the brand’s appeal has always been sensible gear at accessible prices rather than cutting-edge materials. Customer rating is 4.4 stars.

Why it made the list: it is the pragmatic single-pack answer. For someone who does long day hikes, the occasional overnight, a bit of travel and the odd festival, a pack that is usable across all of those beats owning a perfect pack for one of them. The fit adjustment means it can be set up properly rather than tolerated.

What you give up: a pack designed to do several things does none of them as well as a specialist. It is not as comfortable under a heavy multi-day load as the Osprey, and it is bulkier and heavier than a dedicated daypack. Check the specific capacity of the version you are buying, because the Asher is sold in more than one size and the listings are similar. The suspension is functional rather than sophisticated. And as with any pack at this price, the zips and buckles are the components that will eventually define its life.

Who it is for: people who want one pack, mixed use across day hikes and overnights, travel, and anyone who values versatility over optimisation.

Looking after it

• Empty it completely after every trip. Food crumbs attract rodents, which chew through pack fabric in a garage over winter.
• Hand wash, never machine wash. A washing machine destroys frame sheets, padding and coatings. Use lukewarm water, mild soap and a soft brush on the dirty areas, rinse thoroughly and air dry out of direct sun.
• Wash the hip belt and shoulder pads properly if you sweat heavily. Salt in the padding degrades the foam and the fabric over time.
• Dry it fully before storing, hanging or loosely stuffed, not compressed. A damp pack in a cupboard grows mold on the coatings.
• Store it loosely with the buckles undone so the webbing is not permanently tensioned.
• Repair small tears immediately with fabric repair tape. A tear in a loaded pack grows fast.
• Lubricate zips with a dry zip lubricant if they stiffen, and keep grit out of the sliders.
• Check the stitching at the hip belt and shoulder anchor points before a big trip. Those are the highest-load seams and the first to fail.

Easy mistakes to make

• Buying by your height instead of your torso length. The single most common fitting error.
• Carrying the weight on your shoulders. Hip belt on the iliac crest, tightened firmly, first.
• Buying a bigger pack than you need. It will get filled.
• Trying it on empty in the shop. Load it with something heavy before deciding.
• Ignoring the load lifter angle. Roughly 45 degrees means the torso length is right; flat or vertical means it is not.
• Trusting a raincover to keep things dry. Use a liner inside as well.
• Machine washing it. It wrecks the frame and the coatings.
• Going from no pack to a loaded multi-day pack in one step. Build up, especially before a big trip.
• Loading a child or teenager like an adult. Far less weight, and a youth pack with an adjustable torso.

Frequently asked questions

What size backpack do I need?

For day hikes, 15 to 25 liters. For long day hikes and lightweight overnights, 30 to 40. For most multi-day trips, 50 to 65 — that is the range backpacking packs cluster in for good reason. Above 65 liters is for winter trips with bulky insulation, expeditions, or carrying a share of a group’s gear. If you are between sizes, take the smaller one: a pack gets filled to its capacity, and the smallest pack that holds your actual kit is the lightest one you will carry.

How do I measure my torso length?

Tip your head forward and find the bony bump at the base of your neck — the C7 vertebra. Then put your hands on your hips with thumbs pointing backwards and locate the top shelf of your pelvis, the iliac crest. Have someone measure along your spine between those two points. That measurement in inches is what pack sizing is based on, roughly: under 16 extra small, 16 to 18 small, 18 to 20 medium, over 20 large. Your height is not a reliable proxy for this.

Should the weight be on my shoulders or hips?

Your hips, and by a wide margin — a correctly fitted pack puts most of the load through the hip belt onto your pelvis, with the shoulder straps only stabilising it. Fasten and tighten the hip belt first, positioned wrapping the bony crest of your pelvis rather than around your waist, then snug the shoulder straps without pulling the load off the belt. If your shoulders ache after a day, either the belt is in the wrong place or the torso length is wrong.

How much weight can I carry?

A common guideline for a fit adult on a multi-day hike is no more than about 20% of body weight, with 25% as a limit rather than a goal, and around 10% for a day hike. Children and teenagers should carry considerably less, often quoted at 10 to 15%. Build up gradually rather than going straight to a heavy load, and remember that descending with a heavy pack is where knees and ankles get tested. If you have any back, hip or knee problem, ask a physiotherapist or doctor before loading up.

Do I need a women’s-specific pack?

It is worth trying one. Women’s packs generally have a shorter torso range, narrower and more contoured shoulder straps, and a hip belt shaped for a different pelvis, and for many women the difference in comfort is substantial. Some women fit unisex packs perfectly well, and some men fit women’s packs better. Fit is individual; the label is just a starting point.

Are rain covers worth it?

Partly. A cover keeps the outside of the pack from soaking up water, which saves weight in prolonged rain, and it does not keep the contents dry — water runs down your back inside the cover, and seams and zips leak. The reliable approach is a liner inside the main compartment, a dry bag or heavy-duty trash bag, plus your sleeping bag and spare clothes in their own dry bags. Do both in serious weather; do the liner if you are only going to do one.

Can I wash a hiking backpack?

By hand only. Never in a washing machine, which damages frame sheets, crushes padding and strips water-repellent coatings. Empty every pocket, remove the frame if it comes out, and wash with lukewarm water, a mild soap and a soft brush, concentrating on the hip belt and shoulder pads where sweat accumulates. Rinse thoroughly, and dry it fully out of direct sunlight before storing, because ultraviolet light degrades pack fabrics.

Internal frame or frameless?

Internal frame for almost everyone. It transfers load to the hip belt properly and carries heavy weights comfortably. Frameless packs save a couple of pounds and work well below about twenty pounds of total load, provided you pack them carefully so the contents provide the structure — which is a skill. Ultralight hikers with very light kit use them happily; anyone carrying a normal tent, sleeping bag and several days of food should not start there.

Short version

Measure your torso before you shop. That number, not your height, decides which pack size fits, and nothing else on this page matters as much.

For multi-day trips, the Osprey Atmos AG 65 is the most comfortable pack most people will ever carry, and the suspension is worth the money if you are carrying real weight. On a budget, the Teton 65L Scout has the adjustable torso that makes a pack fit properly, which is most of what comfort is. For maximum volume at minimum cost, the Naturehike 65L Rock.

But be honest about what you do. For most hikers the right answer is smaller: the Maelstrom 40L for long days and lightweight overnights, the Gregory Arrio 24L for day hikes with a back panel that keeps you cool, or the Kelty Asher if you want one pack that covers all of it reasonably well.

Whatever you buy, fit the hip belt on the bone of your pelvis first and tighten it firmly, check the load lifters leave the harness at about 45 degrees, and put a liner inside rather than trusting a raincover. Then take a smaller pack than you think you need, because you will fill whatever you buy.
