Backpack technical tests
We carry out laboratory tests to validate all component parts: fabric, buckles, straps, foam and zips. For example, for fabric: resistance to wear, tearing, colour-fastness under UV rays, washing, waterproofing. 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 weighted then placed on a dummy which then reproduces the movement of fast walking over thousands of cycles.
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 these balls into a graduated container, which gives the equivalent volume in litres.
How to adjust your backpack?
1 - Loosen all the straps (straps, hip belt, load adjuster straps). 2 - Put the backpack on. 3 -Tighten the shoulder straps. 4 - Adjust the load adjuster straps as needed.
