HotWool Polo


ACLIMA HOTWOOL® POLO is a more robust base layer top for activities in freezing temperatures. Its thicker Merino wool composition makes for a durable and warm base layer due to its wool/polyester/polyamide blend. HotWool’s terry interior creates insulative air pockets that trap the wearer’s body heat. This trait has made Aclima® HotWool a go-to base layer for Special Operations Forces in cold climates. Layer the HotWool base layers over the WoolNet layers for extreme cold environments when maximum insulation is required.


We have partnered with Norwegian wool specialists, Aclima® to bring you an innovative and military-tested base layering system. Aclima® is family-owned and has been developing cold weather solutions since 1939. They specialize in Merino wool base layers for all climates, activity levels, and professions. Wool has the unique ability to insulate as well as wick moisture from the body. It also has a natural anti-microbial trait that reduces odor. The HotWool layers integrate with our G3 and G4 uniforms. They can be worn underneath in cold environments to add scalable layers of insulation. These unique features and Aclima’s creative design made them the logical choice for our Alpine Terrain Operations (ATO) cold weather line.
