The technical properties of polyester-propylene yarns make the Castelli Core Seamless Long Sleeve Base Layer warm, soft and stretchy, for a close yet unrestrictive fit under your jersey. Effective moisture-wicking draws sweat away from the body to keep you fresh and dry, and the seamless construction prevents chafing. With a wide neck opening, this base layer sits well even under jerseys with a low cut collar.
