Never worry about frozen legs again with the Orage Tundra Hybrid men's insulated pants. Their eco-friendly Primaloft® Thermoplume insulation and DWR water-repellent treatment are perfect for cold days on the mountain, or when you are going to your training session on a chilly morning. This insulating garment can be worn alone or as a mid 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.
