Rapha Pro Team Sleeveless Race Base Layer This high-performance Rapha Pro Team Sleeveless Race Base Layer uses an extremely lightweight, breathable recycled mesh fabric to wick sweat away from the skin. Moisture is rapidly drawn to the surface, keeping you dry while delivering a natural cooling effect when intensity and temperatures rise. The close, race-ready fit is designed to sit perfectly under all cycling jerseys, particularly aero-fitting jerseys, acting as a smooth comfort layer between bibs and jersey during hard efforts and long days on the bike. Designed with modern aero riding in mind, the low scoop neckline ensures the base layer remains completely hidden beneath your aero jersey for a clean, professional finish. Flatlock seams prevent chafing, while anti-bacterial and wicking treatments help the fabric stay fresh even during the toughest sessions. With recycled content reducing environmental impact and class-leading thermoregulation enhancing performance, this base layer is the ideal choice for cyclists who demand race-level comfort and efficiency from Rapha.
