The O'Neill O'riginals men's non-insulated winter sports pants with bib are made with a breathable fabric covered with a 20K/20K waterproof membrane that offers superior resistance to moisture and elements. Those pants are ideal for the skiers and snowboarders that want to spend their days on the slopes in total comfort. This non-insulated shell 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.
