The Outdoor Research Helios Sun Hat is a bucket-style hat for keeping the sun off when you're camping, paddling, or hiking. The 100% nylon fabric is lightweight, breathable, and water-resistant. It wicks sweat, dries fast, and even offers UPF 50+ sun protection. The fit can be dialed in with the crown adjustment or chin cord, as well as completely removing the chin cord if desired. Soak up the outdoors, without letting the sun get to your head.
