The Craft Shield arm warmers are water repellent and warm, entirely according to the new "all weather" trend! The Craft Shield arm warmers can be used during your bike ride on your race- or mountain-bike in cold temperatures. The inside of the arm warmers is equipped with a warm brushed fabric which makes this fabric perfect for when the temperatures drop, for example, early in the morning or in the mountains. They are easy to put on and off during your ride. The arm warmers are very visible in dark conditions thanks to the reflective elements.
