The Rapha Thermal Arm Warmers add the versatility of your favorite cycling jersey, providing an extra layer on colder rides that can be peeled off when the temperatures rise. Made from a high-stretch material with a brushed inside, the Rapha Thermal Arm Warmers lie comfortably against the skin and provide plenty of warmth when the weather turns cold. The seams have all been carefully positioned so as not to hinder movement and at the top, the elasticated support band is intended to be placed under the sleeves of your undershirt. Wear these arm warmers with a windbreaker vest and you'll see, you won't be wearing your winter jersey anytime soon.
