The Assos LS.SkinFoil_S7 Spring/Fall is a short sleeve base layer, for anything but the hottest temperatures. The base layer is the perfect first layer for under your jersey or jacket in mild conditions in spring and autumn. It has a very good fit, and at warmer temperatures it provides excellent moisture transport. Moreover, at colder temperatures this base layer helps keep you warm. By wearing multiple layers of clothing, it can therefore perfectly be used as a first layer on the skin in colder conditions.
