展开Ultralight and ultra smart, the BUFF Pack Run Cap is built to go the distance. Super streamlined, exceptionally light and highly compressible, its comfortable for the long-haul, but can easily be folded and rolled to stash in a pocket. The four panel design and stretch materials hug the head for a secure fit that doesnt bind, while a low profile sweatband provides moisture control without added bulk, and the polyester materials wick away perspiration. The crushable polyurethane brim snaps back to shape and combines with the UPF protective materials for sun protection on long races and extended training days.
