A jacket with a membrane can withstand storm warnings and days of non-stop freeriding without rest or sleep. The figures 17k/20k refer to waterproofing and breathability. No matter what you do, you won’t sweat, won’t freeze, and you’ll be the happiest person on the slopes. The adjustable skirt at the hips prevents snow from getting under the jacket, fitting just right. A headphone flap, ski pass pocket, and essential small features add a delightful touch to the overall comfort.
