A wildly ambitious design centred on cranking up the A/C. This long sleeve, race-ready top is built to maximise Radical AirFlow innovation and is designed so more air flows directly to your skin as you push the pace. Worn and tested by elite ACG Trail Running athletes, Radical AirFlow produces peak results. Your turn to feel the chill.
The Radical AirFlow is Nike's newest innovation, designed to keep trail runners and athletes cool in the hottest environments. Featuring an engineered knit fabric combined with hydrophilic chemistry the top manages moisture and enhances airflow to keep you cool, dry and comfortable on tough trails. A unique construct, the Radical AirFlow Top features an extremely breathable, open-hole design, which helps to channel more airflow directly to your skin for rapid sweat evaporation during movement. The engineered air ducts keep trail runners cool when they're in motion, to maximise the body's natural cooling mechanism. This unique design and flat seams remain soft and smooth against your skin, reducing the likelihood of irritation or chafing, and keeping you focused when tackling the grueling miles ahead. Enhancing performance, the garment is ultra-versatile and built for superior mobility, thanks to flexible materials and a cropped design. The openings at the arm bends and armpits increase ventilation and mobiility, whilst the slight crop at the waist provide you with better access to your running belt, pockets or packs. Finally, the top features ACG branding on the chest, and ACRD branding on the back for added style.
As one of the largest field test initiatives in Nike Running history, members of the All Conditions Running Department (ACRD) tested the prototype throughout the 2025 elite season, tracking feedback from in-race and lab testing to refine the garment.
