20 Litre backpack

I use these as stuff sacks rather than backpacks. A hammock plus tarp ropes and carabiners all fit into this compact pack ready for instant use. I can have my cleeping quarters erected between trees in under 2 minutes.

Compact lightweight

Love the roll up top and compression cord on the front. Easy to pack away and the price is sensible. Will be taking this on my Camino this year to carry shopping etc.

Compact but roomy

A small backup bag to keep in a pocket, but easily converts into a 20l rucksack for handsfree carrying. Lightweight and, whilst it lacks padding for heavy or long distance use, it's perfect for emergencies, unexpected purchases or to stuff discarded clothing in so perfect to take out and about 'just in case'. I debated buying this but the price made it worth a risk and actually I used it every day on a weekend away so I don't hesitate to recommend it.

Xmas present

Bought it for a present. Good quality good price. Can be used for any occasions. Hope the recipient likes the gift.

Well-designed but not durable

A very nice little bag that can carry a surprising amount, both in volume and weight. The waterproof inner coating of the upper roll section is not that durable, however: after one short trip it was already starting to come away, and after three uses cannot be relied upon to protect the contents of the bag from rain. If a more durable waterproof fabric were used for this roll section it would be an excellent product, but as it stands, my recommendation is hesitant as it may only have a short service life.

Flimsy - but waterproof & all I really needed.

This is great because it is lightweight and waterproof, but i am worried how long the straps will last as the material is very thin! However, the fact that this folds up into a tiny little bag is wonderful. The fold & clip top is secure & doesn't come unravelled which is nice. Overall would recommend, but not for those that need a durable bag.

Waterproof Ultra Compact 20 litres Extra Backpack

This rucksack squashes down in to a tiny integral stuff bag and has very good capacity and strength given the lightness of materials and price. It's actually the perfect shape to keep a pair of diving fins in if touring sandy places. No external pocket means it's not for repeated super quick access as you must unwind the waterproof closure but that's no great hardship. Surprisingly strong and roomy. Waterproofness didn't really get tested on my 2 weeks beach hopping and exploring trip.

Additional Product Information


Main fabric

  • 100% Polyester cationic

Backpack technical tests

We conduct laboratory tests to approve the components: fabrics, buckles, straps, foams, zippers, etc. For example, for a fabric: resistance to wear, tearing, colorfastness in UV rays, washing, waterproofing, etc. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to assess the strength of the assembly. The pack is filled with weights and placed on a dummy that replicates thousands of cycles of a fast walking motion.

How is backpack volume measured?

The volume of each backpack is measured using a standardized method: we fill the main compartment as well as each pocket with little balls. Then we empty the balls into a graduated container to find out the equivalent number of liters.
