If you want the protection of a hat while also feeling the breeze on your head, the Nike ACG Radical AirFlow Fly Cap is up to the task. This cap features an open-hole construction for a highly breathable experience, working hard to keep you cool. As you work up a sweat, this technology moves sweat off of your skin for faster evaporation, letting you focus on crushing the next mile.

If you need to adjust for a more secure or loose fit on the move, the hook-and-loop back closure lets you quickly shift for a custom comfort experience. Innovated for the trails, made for anyone, the Nike ACG Radical AirFlow Fly Cap ushers in a cooling breath of fresh air on every run.
