A cool weather cycling kit is not complete without a set of Arm Warmers like Gore Bike Wear's Universal Thermo. They are made with an optimized mix of nylon and elastane, with a brushed interior that feels great against the skin, and an articulated shape to enhance mobility. This natural shape assists the elastic band and silicone grippers to keep the warmers firmly in place. It also permits a next to skin fit that enhances thermal and wicking properties. Gore Bike Wear also uses flatlock seams throughout the Universal Thermo warmers as another tactic to avoid irritating the skin. Finally, reflective logos on the sides add low light safety visibility, and a screen print makes finding left and right easy. The Gore Bike Wear Universal Thermo Arm Warmers come in sizes X Small through X Large and in either White or Black.
