The TNF Sidecut GTX men's winter sports jacket is made with a 3L Gore-TexTM waterproof membrane and has slope style on absolute lock. Featuring select alpine-specific characteristics such as a helmet-compatible hood this outer layer will make it an essential part of your powder day uniform. Perfect for layering, this waterproof shell provides effective protection against the elements so you can stay comfortable all winter long. This garment can be worn as an outer layer in a layering system providing comfort and warmth enabling you to regulate your body temperature by wicking moisture away during your outdoor activities. This onion layering system is made of three types of clothing. 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 or 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.
