Extend' system
This duffel bag is equipped with our "Extend" system, which allows you to vary the volume of the bag. It's a system of straps that allows you to release additional volume by loosening them. Conversely, it can also be used to compress the bag to its minimum volume (40L for this one).
How is bag volume measured?
The volume of each backpack is measured using a standardized method: we use small balls to fill the main compartment and each pocket. We then empty the balls into a graduated container, which gives us the equivalent volume in liters.
Technical tests
We carry out laboratory tests to validate components: fabrics, buckles, straps, foams, zips... For example, for a fabric: resistance to abrasion, tearing, color fastness to UV, washing, waterproofing...
Then a test on the finished product reproduces the bag's stresses and strains over a period of years, to check the resistance of the assemblies.
