Castelli Thermoflex Leg Warmers

Your legs are your engine, so Castelli designed the Thermoflex Leg Warmers to keep them toasty when you're hammering or warming up in chilly conditions. The microfleece lining makes the Thermoflex the warmest leg sleeves that Castelli offers, and the upper silicone gripper keeps them from sliding down and cramping your pedaling style. They even have low profile ankle zippers, which lets you slide them on and off without breaking a sweat.
