This is the White colorway of ACG's Radical AirFlow Apex bucket hat, a tonal off-white finish across crown and brim. The construction is what sets the piece apart: Radical AirFlow is an open-hole polyester knit Nike built to channel air onto the skin, letting body heat escape and sweat evaporate faster than a solid fabric would allow. The same knit appears on the label's Fly Cap and on its Radical AirFlow tops. A wraparound brim provides shade in all directions, Dri-FIT construction handles moisture, and a woven ACG label sits on the outside. Nike lists the hat as fully polyester with hand-wash care.
Retail is $65, the same as the Anthracite version, and both are scheduled for July 29, 2026 at 10:00 a.m. Eastern. That morning slot also covers ACG's Radical AirFlow Fly Cap and the Chamo Camo apparel group of cotton-blend tees, brief-lined shorts and a women's tank. Later the same day, at 5:00 p.m. Eastern, the Radical AirFlow tops and tanks that use the fabric on garments go up, ranging from $110 to $150. Between the two hat shapes, the Apex is the wider-brimmed option and the Fly Cap the adjustable one.
