Endura's Thermolite Tights are warm enough for riding, running or even cross-country skiing thanks to their Teflon treated Thermolite fabric that insulates, keeping you comfortable in harsh conditions. Double-thickness knee panels add warmth and protection, while reflective logos on the thighs and rear of the tights help keep you visible when you need it most. And, with self-locking ankle zippers and silicone leg grippers, you can rely on a snug fit that stays in place no matter how hard you push.
