Attaquer Base Layer - Winter Short SleeveThis double textured, short sleeved compression jersey provides superior insulation during the colder months of the year. Made from Dryarn the winter undershirt is constructed from an inner layer of polypropylene which expels sweat, and an outer layer of PBT polyester which speeds up drying. The result is an undershirt which prevents moisture build up to keep you warm. As a reliable base layer, it's perfect for pairing with our Storm and Race jackets
