Climawarm
Climawarm is a lightweight, breathable insulation that keeps you dry and comfortable in cold weather conditions. It works by using densely woven synthetic fibers that trap air in to keep you warm while at the same time the fibers are spaced far enough apart to easily allow sweat to escape through evaporation.
