Built for hot days, hard efforts and everything in between, the Nike ACG Radical AirFlow Fly Cap is designed to maximise airflow when you need it most.
Powered by Nike’s innovative Radical AirFlow fabric, the cap features an ultra-breathable open-hole construction that channels air directly to your head, helping heat escape and accelerating sweat evaporation as the pace builds. Lightweight and incredibly ventilated, it was developed and tested alongside elite Nike ACG trail athletes to perform in demanding conditions.

The soft knit fabric sits comfortably against the skin, while Nike Dri-FIT technology actively wicks sweat away to help keep you cool, dry and focused. A low-profile design provides a secure, distraction-free fit, complemented by an adjustable ACG hook-and-loop closure for quick, on-the-go adjustments.
