Rank #6 in Best Hiking Backpacks 2026: 10 Ranked, and Only Two Match Their Litres
Bseash 40L Waterproof Hiking Backpack, Black
Price and rating as shown on Amazon when we collected them. Both change.
The Bseash 40L Waterproof Hiking Backpack sits sixth in this guide at £22.99, and of the ten packs here it is the one that comes closest to the volume in its own name without reaching it. The listing gives the size as 58 x 32 x 18 cm. Multiply those three numbers out and you get 33,408 cm³, or 33.4 litres — 6.6 litres, about 16.5%, under the 40L printed in the product title. Elsewhere in this guide the same sum leaves a pack sold as 50L at 27.9 litres and one sold as 70L at 20.1 litres, so 16.5% is not the worst gap we found. It is still a gap, and a soft bag that bulges when packed is the reason to read 33.4 litres as a floor rather than a fixed figure.
The rest of the fiche has loose ends of its own. The 4.5 rating is shown next to 247 ratings, but the star breakdown printed underneath adds up to 100 — 73 five-star, 12 four-star, 9 three-star, 3 two-star and 3 one-star — and those 100 average 4.49, which is the 4.5 on display. The bullets describe the shell as nylon and as ripstop polyester in the same sentence, while the spec table lists a nylon outer, a nylon lining and a polyester fabric type. Everything on this page comes from the Amazon listing and the reviews left on it; we have not handled or tested this pack ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Bought these for my 9 years olds to go camping with cubs. For the price I'm really impressed. They are spacious, supportive and the straps are fully adjustable. They haven't used them yet so can't comment on durability. They have loads of compartments and clips, I especially wanted straps to hold the ground mat and sleeping bag which they have. They even come with a waterproof covering which I thought was good although probably not needed.”
Verified purchase“Very pleased with this rucksack, it has one large main pocket which is what I needed and very supportive waist straps. Seems to be well made and feels comfortable to wear.”

Questions people ask
Is the Bseash 40L backpack actually 40 litres?
The listing states the size as 58 x 32 x 18 cm. Multiply those together and you get 33,408 cm³, or 33.4 litres. A soft bag bulges when packed, so treat 33.4 litres as the floor rather than the ceiling, but it is 6.6 litres short of the 40 in the product name.
What is the rating and how many reviews back it?
The listing shows 4.5 out of 5 from 247 ratings. The star breakdown printed beneath it totals 100 ratings — 73 five-star, 12 four-star, 9 three-star, 3 two-star, 3 one-star — and those 100 average 4.49.
What is the Bseash pack made of?
The listing does not settle on one answer. The bullets call it nylon fabric and then high-quality ripstop polyester, the spec table gives a nylon outer, a nylon lining and a polyester fabric type, and the water resistance level is listed as water resistant, not waterproof.
Does a rain cover come with it?
Yes. The listing says an extra rain cover is included in the bottom of the bag, and rain cover and waterproof appear in the special features. The separate water resistance level is given as water resistant.
What can I carry in it?
The listing gives 5 compartments and 4 pockets, including a utility pocket, an internal pocket for a water bladder and a laptop compartment for devices up to 15 inches, with a maximum weight recommendation of 15 kilograms. It also lists adjustable padded shoulder straps, a chest strap and a padded mesh back panel.
Does the 3 or 4 day trip claim in the listing hold up?
The bullet says the pack meets the size requirements of most airlines and is enough room for 3 or 4 day trips. The size printed in the same listing, 58 x 32 x 18 cm, multiplies out at 33.4 litres rather than the 40L in the name, so how far that goes depends on the pack bulging past its printed dimensions.
