Get ready to combat the cold with our ECWCS Gen III Level II Underwear Bottoms. Made from breathable, mid-weight grid fleece material that is great for layering, the thermal base layer military underwear is designed to keep you warm, comfortable, and dry, even in the harshest weather. The waffle thermal also features anti-microbial and anti-odor defense, ensuring that you stay fresh and clean through winter combat missions and cold weather activities. Stay Warm & Dry: The base layer pants wick sweat and moisture away for optimum comfort, swiftly transferring it to the top layer for a quick dry. This allows you to move freely without your clothing sticking to you, ideal for winter operations, hiking, camping, skiing, snowboarding, hunting, and other outdoor activities. Comfortable Fit: Built from a soft polyester / spandex blend, the grid fleece fabric easily flexes and contorts with your body for optimum comfort. The base layer pants feature an access fly, along with an elastic waist and leg bottoms that help insulate your body heat. Active-Duty Approved: The thermal bottoms are part of the Extended Cold Weather Clothing System (ECWCS) and are a must-have for any military personnel, tactical professional, or outdoor enthusiast in cold climates. Whether you are gearing up for a mission or camping up in the mountains, you will want to keep a pair on you. Better Together: Stay warm and comfortable this winter with our matching ECWCS Gen III Level II Underwear Tops. The base layer shirt features the same breathable, mid-weight grid fleece material as the bottoms, ensuring that you’re ready for the mission at hand.
