Materials

100% ripstop-reinforced polyamide (weight 80g/m2), PU-coated on the inside. The PFC-free Bionic-Finish Eco treatment makes the fabric more water and dirt-resistant. We stabbed and tried to rip the fabric, the ripstop is what it is supposed to be.

Waterproof rating (hydrostatic head) at least 5,000 mm, so the cover will keep the water outside even in heavy rain. Note that water didn’t start getting through at this mark; the test was simply stopped there. So, this is the minimum; the maximum isn’t known.
