The beauty of the Garneau's Course WindPro Arm Warmers is that they allow you to create a riding kit that will adapt to changing weather throughout your ride. They're made from fabrics that offer warmth, wind protection, moisture control, and a light compression. At the biceps, Gladiator Grip keeps them in place without any bulkiness. These arm warmers also provide comfortable flatlock seams and UPF 50 sun protection. Enjoy the Course WindPro Arm Warmers until your body temperature rises and then stow them in your back pocket for the next descent!
