Klim Aggressor 1.0 Base Layer Shirt Mens Large L Black Pullover Crew Snow Sports

Not all base layers are created equal and like everything else Klim does they have found a way of improving on something as seemingly simple as a moisture wicking base layer. The Klim Aggressor Cool -1.0 Long Sleeve shirt uses Klim's own chemical free cooling technology. This isn't a hyped up buzz word either, whereas most garments with moisture wicking use a chemical base that slowly gets "used up", Klim uses a special fabric that will never lose its effectiveness.
