The CCN Sport Aero Cycling Cap is made of a lightweight and quick drying fabric which easily fits under your helmet. The peak keeps the sunlight from blinding your vision whilst the fabric takes the moisture away, ensuring sweat doesn’t run into your eyes. Additionally it works great for cooler rides creating an additional extra layer of warmth. A four panel design and laser perforation at the back to increase air flow and a stretchy elastic back our CCN Sport cycling caps provide a comfortable fit for all head sizes.
