The Outdoor Research Helios Sun Hat gives you dependable shade for long days in the sun. A roughly 7cm (2.75in) brim, UPF 50+ fabric and a light, quick-drying nylon build keep your head cool on the trail, at camp or on the water.

A crown cinch dials in the fit and the detachable chin cord keeps it on when the wind gets up – take the cord off when you don't need it. At 68g it's easy to stash in a pack for the walk-out. Choose the Helios when you want a full-brim sun hat that shrugs off sweat and light showers.
