Our updated Thermal Leg Warmers feature Renew Series; recycled content in the luxurious Super Roubaix material, to reduce environmental impact with no reduction in performance, comfort, or durability. A silicone gripper keeps the cuff secure no matter how hard you ride, helping to fend off cold and damp conditions. These are ideal for use on cold mornings, or anytime you need a little extra coverage, and they stash easily in a jersey pocket when they're not needed.
