Waterproof
Waterproofness is the height of a water column, in mm, that the fabric holds before water gets through. 30,000 mm is a column of water 30 metres high, roughly a 10-storey building, pressing on the fabric.
Lab-tested beyond 61,200 mm: all five fabric samples exceeded the test maximum (JIS L 1092 7.1, Method B). Our requirement for the Barrier CT™ fabric of the AR hardshell is 30,000 mm.

Can I try it on first?
Yes, in our store at Bilderdijkstraat 136HS, Amsterdam.
How do I keep it waterproof?
Wash at 30°C with liquid detergent or a technical wash, without fabric softener. If water stops beading, wash and dry the jacket first, then reapply a water-repellent treatment.
