GOREWEAR Windstopper Thermo Beanie in Black - Size: Medium

From SteepandCheap.com

For chilly commutes and cold-weather training rides, the Gore Wear Windstopper Thermo Beanie protects your head and ears from losing valuable body heat as you ride. A Gore Windstopper membrane prevents wind from stealing your heat without trapping in moisture as you work up a sweat. The synthetic fabric wicks away perspiration, dries quickly, and stretches to maximize comfort throughout long days in the saddle. Gore even added slits above the ears so you can comfortably, and more importantly securely wear your glasses or sunglasses to keep your vision clear.
