TREKKING TREKKING SEVERAL DAYS MOUNTAIN TREKKING BACKPACKING
LEVEL OF PRACTICE
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.
We conduct laboratory tests to approve the components: fabrics, buckles, straps, foams, zips, etc. For example, for a fabric: resistance to abrasion and tearing, colour fastness in UV light and after washing, waterproofing, etc. Then the finished product undergoes an accelerated test replicating the stresses on the bag over several years to test the strength of the assemblies. The pack is filled with weights and placed on a dummy that replicates thousands of cycles of a fast walking motion.
