NWOT Gray climawarm hoodie with drawstring. White adidas logo and lettering. Women’s size small Adidas ClimaWarm is a lightweight, breathable insulation that keeps you dry and comfortable in cold weather conditions by using densely woven synthetic fibers that trap air to keep you warm but are also spaced far enough apart to easily allow heat-sapping sweat to escape through rapid evaporation.
