This duffle bag comes with our “Extend” system so you can vary the bag's volume. It's a system of straps that free up extra space when loosened. Conversely, it also compresses the bag to reduce it to its minimum volume (40 L for this one).
How is bag volume measured?
The volume of each backpack is measured using a standard method: we use small balls to fill the main compartment as well as each pocket. We then empty the balls into a graduated container, which provides the equivalent volume in litres.
We complete laboratory tests to certify components: fabrics, buckles, straps, foam, zips... for example, for a fabric: resistance to abrasion and tearing, colour-fastness in UV light, resistance to washing, waterproofing, etc.
A test is then conducted on the finished product replicating the accelerated demands on the bag over the years to check the strength of the assembly.
