Keep the sun off your face, the rain from your eyes, or add a touch of warmth under your helmet with this highly technical cycling cap. Rapha has redefined the classic cycling cap here, eschewing the traditional heavy cotton construction for a synthetic fabric which offers stretch for a perfect fit, as well as wicking qualities to stop overheating. The iconic style of the cotton birettas isn’t lost, however. This lightweight, peaked version has a low profile, so fits very comfortably under a helmet, while a soft, stretch anti-bacterial tape around the inner rim helps it stay in position. The cap’s seams are engineered to provide the lowest-possible profile, while other performance details include a reflective logo and top-stripe, and laser-cut ventilation holes on the sides. The cap is designed to pair with any of the Rapha Pro Team collection, keeping you sharp on your fastest rides.
