Anyone who’s ever finished an outdoor adventure race of any stripe, from trail running and obstacle racing to mountain biking, will have encountered BUFF, or at least a knock-off version of their iconic neck gaiters. The ubiquity of that versatile design within the adventure world is perhaps the biggest compliment to BUFFs meteoric success. That fusion of a breathable, moisture-wicking fabric and a stretchy, shape-shifting design is perfect for high-octane events and morning dog walks alike.
