The Tru-Spec Generation III ECWCS Level 1 Bottom is a type of base layer designed to be worn next to the skin in cold weather conditions. "ECWCS" stands for "Extended Cold Weather Clothing System," and this layer is part of a multi-layered clothing system developed by the United States military for use in extreme cold weather environments.

The Level 1 Bottom is made from a lightweight and breathable fabric that is designed to wick moisture away from the skin, keeping the wearer dry and comfortable. The fabric is also treated with an antimicrobial agent to help reduce odor-causing bacteria.

The bottom features an elastic waistband and a functional fly, as well as a tapered leg design that reduces bulk and makes it easier to layer additional clothing over the top. The cuffs are also elasticized to help keep them in place and prevent cold air from entering.

Overall, the Tru-Spec Generation III ECWCS Level 1 Bottom is a high-quality base layer that is designed to provide warmth, comfort, and moisture management in cold weather conditions. It is a popular choice for military personnel, law enforcement officers, and outdoor enthusiasts who require reliable performance in harsh environments.

The Extreme Cold Weather Clothing System, or Gen-III ECWCS is a protective cold weather clothing system created originally by the United States Army Natick Soldier Research, Development and Engineering Center. This system consisted of a parka and trousers plus 20 other individual clothing, headwear and footwear items which are used in various combinations to meet the cold weather environmental requirements of the US military. Our baselayer level garments are based off these designs to give our garments the same quality and utility as the base layers of this system. The Level-1 garments draw moisture away from the skin to the outer layers of clothing providing great warmth without weight, is fast drying and compresses to reduce volume when packed.
