The Outdoor Research Sun Bucket Hat protects your head from the sun on bright bluebird days in the outdoors. With UPF 50+ SolarShield fabric defending your melon from the sun's rays, the Sun Bucket hat offers protection that no sunscreen can touch. Outdoor Research gave this summer hiking hat a Coolmax headband to wick the sweat away and a removable drawcord to keep this cap firmly planted on your head if the wind picks up on the trail.
