The third generation of the Extended Cold Weather Clothing System is the most advanced iteration by the U.S. Army to date. Seven levels of intuitive, combat-ready clothing work in concert to provide optimal temperature calibration in sub-zero conditions. This latest generation is 25% lighter than previous versions, takes up 33% less space and offers protection down to -60°F. Driven by insulation, layering and ventilation, Gen III resists the transmission of heat away from the body, increases layered air spaces to maintain warmth and allows moisture to escape from the body. Intuitive Polartec and PrimaLoft fabric technologies fuse the latest innovations with classic designs to ensure soldiers are comfortable, mobile and ready for battle in the most extreme climates.
