Helly Hansen's thermal combination suit in Heavy Weight Poly-Pro will keep you warm and dry even in the most miserable weather. Poly-Pro works on the principle that wet skin becomes cold skin, leading to chilling and even hypothermia. Poly-Pro effectively wicks moisture away from the skin pushing it to an outer layer, allowing you to continue your cold-weather activities in comfort. The Poly-Pro combination suit features flatlock seams, full button front, and rear "trap door" with button closure.

Note: This product is excellent when moisture is an issue.
