The C3 Thermo Leg Warmers are Gore Wear's solution for shoulder-season rides that either start or end in vastly colder conditions than the bulk of the ride. Enjoy most of your ride in your shorts while the sun keeps you comfortable, but for the part of the ride before dawn or after dusk--pull on these leg warmers to keep your muscles warm. They use synthetic material that traps in heat yet breathes to manage moisture, and have pre-shaped knees so you can keep pedaling without the discomfort of bunching. An elastic cuff at the top provides stable positioning with an optimal fit, and the base features a semi-locking zipper which makes the warmers easy to remove or add without taking off your shoes.
