Skull Caps

Cycling Skull caps are designed to wear under your helmet and are used to keep sweat out of your eyes.

Summer Skull Caps

Summer skull caps are made of light-weight highly breathable fabrics that are designed to wick moisture and breath. They allow your head to remain cool, but prevent sweat from dripping into your eyes.

Winter Skull Caps

Helmets have large vents designed to make the helmet lighter and to provide airflow so that the cyclist doesn't overheat. That is great for summer cycling, but not great for riding in cold weather. Winter skull caps are designed to protect  your head from wind and to keep your head warm. They are usually made of thermal fabrics that stretch like polypropylene or fleece. They can be designed to cover your ears, or just the top of your head.
