Travel Ultra-Compact 10 Litre Rucksack - Purple

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 which gives us the equivalent number of litres.

Backpack technical tests

We conduct tests on all the component parts in the laboratory:

fabric, buckles, straps, foam and zips. For example, for fabrics:

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.
