Ideally suited for early spring, late fall, or temperate winter days, the breathability and thermoregulating qualities of the R Winter Arm Warmers P1 provide total comfort in cool, wet, and windy conditions. The warmers’ textile is upgraded for increased warmth – even in wet conditions – and when the temperatures rise and the road dries, they still pack down to stow in a jersey pocket. For added versatility, the low-volume, second-skin fit layers easily beneath wind and rain shells, adding insulation to stormproof protection.
