We conduct laboratory tests to approve the components:
fabrics, buckles, straps, foams, zips, etc. For 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 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 standardised 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 litres.
