The Assos Summer Sleeveless Skin Layer is a lightweight and breathable layer that keeps your core temperature comfortably regulated through the hottest and most humid days of the year. This version is 30 percent lighter than its predecessor, making it an even better choice for summer. A circular knit pattern avoids any irritation from side seams which is ideal against the skin and for interacting with the layers above. The blend of materials were chosen specifically to manage all of the moisture that is associated with hot summer rides, keeping you feeling comfortable and dry regardless of how much effort you put in. The Assos Summer Sleeveless Skin Layer is lightweight, breathable, form fitting, and anti-bacterial for the perfect summer feel.
