Gear Review: Patagonia Air Flow Cap

As cool and breezy as a visor—but with superior sun protection (15 UPF)—this cap kept our tester cool during morning runs and afternoon summit climbs. The full-size, moldable brim provides effective shade. An elasticized rear buckle cinches tight so the cap stays put on windy peaks, and carbon particles adsorb the bacteria that causes fabrics to stink.
