Outdoor Research Helios Sun Hat Neptune, XL

That small, exposed piece of scalp on the back of your head serves as a very painful reminder that you're going bald after a long day out in the sun-save yourself the burn and unwanted reality check with the Outdoor Research Helios Sun Hat. Made with Outdoor Research's SolarShield material, the Helios offers UPF 50 sun protection and is designed with a wide brim to effectively shield your face from the sun's rays. The elastic drawcord keeps the hat glued to your melon when you're floating down a windy river, and the adjustable chin strap serves as a fail safe, just in case you start to feel the Helios peel back from your head under pressure from heavy-handed winds.
