We carry out lab tests to validate all elements:fabric,buckles,straps,foam & zippers.For example,for fabric: resistance to abrasion and tearing, colorfastness in UV light, resistance to washing, waterproofing, etc. Then, a test is conducted on the finished product replicating the accelerated demands on the backpack over a number of years to check the strength of the assemblies. The backpack is weighted, then placed on a dummy that reproduces the movement of fast walking over thousands of cycles.

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 that gives us the equivalent number of liters.
