The NXT long-sleeve is the piece that made Radical AirFlow famous — worn in prototype form by Caleb Olson when he took first at the 2025 Western States 100. Nike's warp-knit spacer mesh is engineered with placed holes acting as air channels; airflow through those channels and the funnel-shaped vents accelerates sweat evaporation, cooling the body far faster than wicking alone. Long sleeves add coverage without adding heat. Dri-FIT.
