23L Skateboarding Backpack Mid - Black

Lab test

We perform lab tests to approve our products' components: fabric, buckles, straps, foam, zips, etc. E.g. for fabric, we test resistance to wear and tearing, whether the colours withstand UV light and washing, the fabric's waterproofing, etc. We then check how sturdy the construction is by performing an accelerated use test on the finished bag that mimics the wear and tear it would suffer over several years.

How do you measure the volume of a bag?

The volume of each backpack is measured using a standardised method: we fill the main compartment and all of the pockets with small balls. We then empty the balls into a container with markings on it that tell us the equivalent volume in litres.
