not sure about the breathability but the waterproof may be a typo.drumheros wrote: ↑"Dermizax Wwb

These look like crap ratings for a waterproof breathable jacket. Depending on what kind of exercise you're doing and in what conditions, you usually want to aim for at least 15k/15k ratings on both waterproof and breathability.

manufacturer website and altitude sports both say "WATERPROOF: - Dermizax 20,000mm"
Most arcteryx jackets use goretex which is 28,000 I believe.
