Nike ACG Radical AirFlow Fly Cap - Open-Hole Knit for Maximum Airflow at Pace

Radical AirFlow is a wildly ambitious fabric centred on cranking up the A/C. This race-ready ACG Fly Cap channels more air directly to your head as you push pace, worn and tested by elite ACG Trail Running athletes. Your turn to feel the chill.

Radical AirFlow Open-Hole Knit Construction

Radical AirFlow features a wildly breathable open-hole construction that channels airflow directly to skin for rapid sweat evaporation during movement. Soft open-hole knit feels smooth against skin and lets body heat escape quickly, most effective during sustained trail efforts when head temperature rises and standard fabrics trap warmth.

Dri-FIT with Low-Profile Secure Fit

Nike Dri-FIT technology moves sweat away from skin for quicker evaporation, working alongside the open-hole construction for comprehensive moisture management at pace. Low-profile design fits snug for a secure feel through tough terrain. Pre-curved bill keeps sun out of eyes during trail running.

Is the Radical AirFlow Fly Cap Right for You?

For trail runners who overheat easily or race in warm conditions where head ventilation makes a genuine difference to comfort and focus. Open-hole knit actively channels air rather than simply using lighter fabric, making this most effective during hard efforts where standard caps trap heat. Low-profile fit stays secure on technical terrain without adjustment. Pre-curved bill handles sun exposure on exposed mountain and trail routes.
