Revolutionary innovation and cutting-edge textile engineering: the Nike ACG Radical AirFlow NXT redefines the standards of the trail running in the most extreme weather conditions.
At the heart of the shoe lies the pioneering Radical AirFlow: an open-mesh structure with extremely high breathability, designed to channel a continuous flow of air directly onto the skin and accelerate the body's natural cooling mechanisms. Tested and refined during the 2025 season by the athletes of the All Conditions Racing Department (ACRD) — and worn by Caleb Olson during his historic victory in one of the world's mostgrueling 100-mile endurance races —, this jersey combines moisture managementwith Nike Dri-FIT technology with engineered airflow channels in areas prone to heat buildup and friction.
Featuring foldable elasticized hems that keep the shirt in place while running and dual ACG and ACRD branding on the chest and back, it's the ultimate shirt for pushing your pace beyond all limits.
