Best Hiking Backpacks 2026: 10 Ranked, and Only Two Match Their Litres

It sits first because the arithmetic holds and the review base is unusually deep. The listing prints 30 x 28 x 48 cm, and that multiplies out to 40.3 litres against a claimed 40L. Meanwhile 3,626 ratings average 4.7, with 83% of them at five stars. No other pack on this page combines a verified size with that volume of opinion.

In practice it is built like a utility bag rather than a trail pack. The shell is 1000D polyester with double stitching and two-way zips, and there is MOLLE webbing front and side for clipping on pouches. A 3L hydration bladder fits the internal sleeve, although the bladder is not included. Two D-rings sit on the shoulder straps. At 1.25 kg it is the second-heaviest of these hiking backpacks.

The catch is weight and care. At 1.25 kg it is heavy for a 40-litre bag, and 1000D polyester is not a lightweight hiking backpack fabric. Hand wash only, no machine cycle. If your priority is a pack that disappears on your back for a day walk, this is not it. If you want one that survives being dumped on gravel, it is.

Second place goes on volume of evidence rather than verified size. It carries 3,422 ratings at 4.5, with 75% at five stars. Worth noting what is missing, though: the listing prints no dimensions anywhere. Unlike most packs here there is nothing to multiply out, so the 40L figure stands as a label with no measurement behind it in the data.

The material spec is 210D rip-stop nylon, the lightest denier on this page, with a rain cover included and stowed in its own pocket. There are seven pockets and eight compartments in total, including two zipped pockets on the waist belt and elastic loops on the sides that hold trekking poles or a bottle. Reflective printing runs across the front. The ring handle and the shoulder straps are padded.

That said, a 210D shell and no stated frame mean this is a day pack, not a load carrier. If you want a waterproof hiking backpack for multi-day trips with 12 kg in it, look elsewhere. If you want a light hiking daypack for a long walk with a packed lunch, a spare layer and a flask, it fits that job.

It earns a place on price and packability rather than measured volume. £21.24 buys a pack with 2,498 ratings at 4.4 and a listed weight of one pound. It folds into its own pocket. Meanwhile the dimension line reads 52 cm deep by 25 cm wide by 33 cm high, which labels the longest measurement as the depth. That is an odd way round, and it makes the 40L claim hard to check against the numbers given.

In practice this is a travel bag with walking features. The nylon is water-repellent rather than waterproof, the main zip is metal with double sliders, and there is a wet pocket for damp kit plus a chest strap with a whistle buckle. Elastic loops on the sides take trekking poles. As a result it packs down small enough to live in a suitcase between trips.

The catch is stretch and structure. The spec sheet lists medium stretch, which is unusual for a pack shell and points to a thinner weave than the 1000D bags above. There is no frame and no hip belt listed. If you want to carry 15 kg up a hill, this is the wrong bag. If you want a lightweight hiking backpack to keep folded in a suitcase, it is the cheapest useful option here.

This is the second of the two hiking backpacks here that survive the arithmetic. The listing gives 21.8 x 34 x 55.9 cm, which works out at 41.4 litres against the 40L name. The bullet text repeats the same figures in inches, 13.4 by 8.6 by 22, so the two lines agree with each other rather than contradicting. It weighs 889 g, making it the lightest pack on this page that carries over 40 measured litres.

In practice the spec is aimed at wet weather. The nylon is listed as waterproof, and a rain cover with a reflective logo sits in the bottom pocket. It has 15 pockets and eight compartments, the highest counts here. There is a hose port and a Velcro loop for a bladder, plus compression straps on the sides and base to tighten a part-full load. The listing also says it meets the size requirements of most airlines.

Even so, 15 pockets is a lot of seams, and seams are where waterproofing fails first. Care is wipe with a damp cloth only, no machine wash. If you want a simple bag for a summer day walk, the extra zips are dead weight and weight you carry. If you hike in the rain and want every small item to have a home, they are not.

This is the clearest example on the page of a label outrunning a measurement. The listing states 40L and then gives 53 x 33 x 20 cm in the same bullet. Multiply those out and you get roughly 35 litres. It is still a decent bag, with 1,753 ratings at 4.5 and 72% of them five-star, but the litre figure is marketing rather than interior space.

The build is rip-stop polyester with a rain cover in its own bottom pouch, an internal water bladder pocket, and reflective stripes on the shoulder straps. There is a breathable sponge back panel and adjustable padded straps. The listed weight is 800 g, and the 1.76 lb printed in the same bullet agrees with it, which is more than some listings manage.

However, machine wash is listed here, which few packs at this price allow. The catch is the shape: 20 cm deep is a slim bag, so a sleeping bag and a tent will not go in together. If you want a hiking backpack with rain cover for a day walk and a waterproof jacket, it is plenty. If you want a camping backpack 40l for an overnight, the real volume will frustrate you at the first packing.

£22.99 buys a rain cover, a padded mesh back panel and a listed laptop sleeve. It also buys a contradiction: the spec sheet gives the closure as a drawstring while the bullets describe zips. And 58 x 32 x 18 cm multiplies out at roughly 33 litres against the 40L in the name. The review base is 247 ratings at 4.5, the second-smallest sample on this page.

At the same time the practical side is sound for the money. Nylon and ripstop polyester, water-resistant and tear-resistant, with the rain cover in the bottom pocket, reflective stripes on the straps, adjustable padded shoulder straps and a listed weight of 1.98 lb. The chest strap and padded back are there too, and the listing claims it meets the size requirements of most airlines.

That said, 33 litres of measured space is a day pack wearing a big label. If you keep a rucksack for hiking in the car for spontaneous walks, it is fine, and it is the cheapest of these hiking backpacks with a rain cover included. If you are buying your only 40l hiking backpack for a three-day trip, pay the extra £6 for the Bseash at £28.99 and get the same rain cover with a 1,753-rating base behind it.

The price is the headline: £15.99 against £79.99 at the other end of this list. However, the listing does not agree with itself. The first bullet says 43L. The storage volume field says 40 litres and the size field says 40L EU. The dimensions line gives 33 x 27 x 52 cm. Between those four lines, the same bag is described three different ways, so check the actual measurements before you trust either figure.

In practice it is a MOLLE platform. There is webbing front and side for pouches, internal hooks for a hydration reservoir with side tubing ports, and bottom compression straps sized for a rolled sleeping bag. Mesh side pockets take 1L bottles. The back panel is ventilated and there is a chest strap to take pressure off the shoulders on a climb. The load recommendation is 15 kg, on a polyester shell, and it weighs 950 g.

Crucially, 132 ratings is a thin base for any purchase, and roughly a quarter of them sit at three stars or below. There is no rain cover in the listing. If you want a cheap second bag to abuse in a car boot, it makes sense. If you need a waterproof hiking backpack for British weather, you will be buying a cover separately.

Position eight goes on the numbers rather than the rating. It carries 4.3 from 1,043 ratings, with 65% five-star, which is the lowest five-star share in the top eight. And the size line is the problem. The listing prints 59 x 25 x 16 cm, and that multiplies out at 23.6 litres against a 40L name. In theory the bag bulges when packed, but that is a 41% shortfall to make up before the bulge even starts.

The rest is familiar from the other Bseash packs. Rip-stop polyester, water-resistant, a rain cover in the bottom pouch, an internal bladder pocket, reflective stripes on the shoulder straps, a mesh back panel and padded adjustable straps. The listed weight is 1.43 lb. A laptop sleeve is listed up to 15 inches.

That said, at 23.6 measured litres there is not much pack here, and unlike its £28.99 sibling no maximum load is stated. If you want one of these hiking backpacks for a commute plus a weekend walk, it will do the job. If you are counting on 40 litres for a bothy trip, you will find out on the first packing.

The listing is confident: 50L, room for three to five days, 0.69 kg. Then it prints 62 x 30 x 15 cm. That is 27.9 litres. Among these hiking backpacks only the 70L pack has a wider gap between the label and the measurement. Meanwhile the same bullet puts the rain cover in a small upper pocket. If you are packing five days of kit, 27.9 litres is a real constraint, and five days of clothing alone will not fit.

In practice it is a foldable travel bag with walking features bolted on. Polyester and nylon, water-resistant, a reflective strip, elastic and mesh on the sides for external kit, a padded back panel and adjustable straps. The material field lists polyurethane while the outer material reads polyester, and the fabric mix is given as 15% nylon and 85% polyester, so those three lines do not quite line up. It is machine washable.

Either way, a 50L label on a 27.9-litre shell is a big overstatement. The 943 ratings at 4.3 with 68% five-star are solid but not exceptional. If you want a packable spare for a flight, it works. If you want the capacity the name promises, you will not get it, and you will be repacking at the airport.
