Hiking in wet weather calls for a bit of extra protection. The Outdoor Research Seattle Rain Hat is one of our favorite hats to wear when hiking in the rain. The 3L GORE-TEX membrane ensures the water doesn't get through and keeps everything underneath the three-inch flat brim dry. An adjustable and removable chin strap allows us to adjust our fit, and a hook-and-loop panel on the side of the temple allows the brim to fold up at the side when the weather clears.
