Our backpacker-designers created this compact bag for carrying the items you need for a one-day trip Ultra-lightweight, discreet and compact bumbag-type belt pouch. Can be folded up and stored in a backpack pocket.
The volume of each backpack is measured using a standardised method: we fill the main compartment as well as each pocket with little balls. We then empty the balls into a graduated container which provides the equivalent volume in litres.
Backpack technical tests
We conduct laboratory tests to approve the components:
fabrics, buckles, straps, foams, zips, etc. Example, for a fabric:
resistance to wear, tearing, colour-fastness 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 backpack is filled with weights and placed on a dummy that reproduces the movement of fast walking through thousands of cycles.
