With a wide brim, breathable Supplex fabric, and a sweat-wicking headband, this hat provides shade and sun-block with a UPF 30 rating. But add the breathable, seam-taped, waterproof shield and it does double duty as a rain hat. And since the rain shield rolls up and stores under the brim, you’ll be ready no matter how quickly the weather changes. The foam-stiffened brim gives the hat shape and structure and helps keep raindrops from getting under your collar, plus it floats, making this had a great choice for boating and kayaking. Features an external adjustable drawstring and a removable chin cord with cord-lock.
