FEEL COOL AND DRY WITH ADIDAS CLIMACOOL Supporting your body’s cooling system through the power of advanced materials. Your sweat is wicked away to evaporate fast and keep you comfortable. Engineered for running, training and outdoor wear. UPF 50 SUN PROTECTION: UPF 50 sun protection shields against the sun’s harmful rays through outdoor training, summer sport, golf rounds and full-day outdoor wear — built for active men who log miles in the sun — so the hat stays put on head. NON-GLARE UNDERVISOR: A non-glare undervisor cuts reflected light off pavement, water and field turf for clearer vision on sunlit runs, outdoor commutes and summer golf rounds — sharper sight for the active man’s outdoor rotation — for no-slip wear through workouts. REFLECTIVE DESIGN ACCENTS: Subtle reflective hits add a sporty, low-light-friendly finish for early-morning runs and evening walks. This product has reflective elements for design and decoration reasons only. It is not intended or suitable for the use as Personal Protective Equipment PPE (e.g. to protect by enhanced visibility) and would not meet mandatory PPE standards. FIT — ONE SIZE FITS MOST MEN: An adjustable hook-and-loop back closure fits head circumferences 21 through 24 inches (53 through 61 cm) — covering the average men’s (23 in. / size L) range. Stretch poly-spandex blend. Spot clean.
