What are the best waterproof backpacks to buy in the UK?
Our top pick for Waterproof Backpacks in the UK is the IDRYBAG 20L Dry Bag Backpack Waterproof Floating (Blue).
The IDRYBAG suits paddlers and hikers who want a 20L roll-top dry bag backpack with welded seals and a reflective strip, per its listing.
The IDRYBAG 20L dry bag backpack is our top pick among waterproof backpacks because its listing states 500D vinyl-coated woven polyester with heavy duty welded and watertight seals, a roll-top closure and a reflective strip. For longer outings, the MARCHWAY Roll Top 30L adds padded shoulder straps with adjustable sternum and waist straps; for work or school, the Lekeinchi 16-20L roll-top laptop backpack holds a 17-inch laptop.
This guide compares five waterproof backpacks from IDRYBAG, MARCHWAY, XREE, Lekeinchi and Lekespring, using what each listing states: capacity, material, closure, seams, straps and pockets. The sizes on these cards run from 16L on the Lekeinchi (expanding to 20L) to 40L on the XREE.
Buying guide
What should you look for in Waterproof Backpacks?
1Capacity: the listings state 20L for the IDRYBAG (also listed in 30L and 40L), 30L for the MARCHWAY (also listed in 20L and 45L), 40L for the XREE, 16L to 20L for the Lekeinchi and 17 litres for the Lekespring.
2Material: the IDRYBAG is 500D vinyl-coated woven polyester; the MARCHWAY is dual-layer waterproof PVC over a polyester mesh core (500D PVC in its title); the XREE is PVC fabric with seamless construction; the Lekeinchi is waterproof and tear-resistant polyurethane fabric; the Lekespring is a waterproof matte leather material.
3Closure: the IDRYBAG and XREE roll down 3-4 times and buckle, and the MARCHWAY rolls down 3 to 5 times with side buckles and a top clip. The Lekeinchi has an adjustable roll-top; the Lekespring closes with a flap and double magnetic closure.
4Seams: the IDRYBAG listing states heavy duty welded and watertight seals and the MARCHWAY states welded seams; the XREE states seamless construction. The Lekeinchi and Lekespring listings say their stress points are reinforced and do not mention welded seams in the features we read.
5Pockets: the IDRYBAG listing says its front pocket is splash-proof rather than completely waterproof and advises against putting a phone in it; the MARCHWAY's external pocket is splash resistant and the XREE's exterior zippered pocket is water-resistant.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.
The Lekespring suits work and school use: a 17 litre flap backpack in waterproof matte leather material with a padded 15.6 inch laptop compartment, per its listing.

Editor's Note
None of the five listings states a warranty term in the features we read. The XREE and MARCHWAY listings give no dimensions, while the IDRYBAG's product details list 21.5 x 13.4 x 7.1 inches and the two laptop backpacks give theirs in centimetres.
Our Take
The IDRYBAG 20L is the default pick for keeping kit dry: 500D vinyl-coated woven polyester, welded seals and a roll-top. The MARCHWAY 30L suits longer outings with sternum and waist straps and side MOLLE loops, and the Lekeinchi suits work or school use with room for a 17-inch laptop and a roll-top that expands from 16L to 20L.
