The Arc'teryx Sabre men's winter sports jacket was designed with specific snowsports features to deliver optimal freedom of motion, breathability and protection. This shell is made of waterproof, windproof and breathable Gore-TexDM, so you can stay comfortable and dry during your descents. Multiple pockets allow you to bring all your essentials with you on the slopes. And when you break a sweat you can unzip the underarm ventilation to keep you comfortable. Layering is the key of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers moves moisture away from your skin, conserves or dissipates heat and provides you with weather protection. Here they are. The first layer, worn next-to-skin will provide warmth and quickly move moisture away from your skin. Then, the second layer, is the insulation and fleece, that provides warmth while also dissipating heat during periods of high output. And finally, the third layer, the shell, which is the most weather-protective layer, worn on the outside of all other layers.
