REVOLUTIONARY INNOVATION FOR ATHLETES IN MOTION.
Radical AirFlow is a wildly ambitious fabric centered on cranking up the A/C. Built to maximize the Radical AirFlow innovation, this race-ready ACG Fly Cap is designed to allow more air to flow directly to your head as you push pace. Worn and tested by elite ACG Trail Running athletes, Radical AirFlow produced peak results. Your turn to feel the chill.

Low-profile design fits snug for a secure feel while you push the pace through tough terrain.
Pre-curved bill helps keep the sun out of your eyes.
Radical AirFlow features a wildly breathable, open-hole construction to help channel more airflow directly to your skin for rapid sweat evaporation while you move.
The soft, open-hole knit fabric feels smooth on the skin and lets your body heat escape quickly. The ACG-branded hook-and-loop closure lets you make easy fit adjustments on the fly.
Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable.
