The Castelli Core Seamless Short Sleeve Base Layer is engineered from a blend of polypropylene and polyester yarns to create a garment that is soft, warm and stretchy. Adding an extra layer of thermal protection under a jersey, it hugs the body without restricting movement and draws moisture away from the skin to keep you dry and at a comfortable temperature. A seamless construction reduces the chances of chafing, and the base layer has a wide neck opening so it fits comfortably even under low-collared jerseys.
