Patagonia Vented Spoon Bill Hat The Patagonia Vented Spoonbill Hat has you covered through rain or shine when you're hiking, camping, or fishing. Supplex nylon covers the brim, front, and back flap with maximum protection from the sun's UV rays, and the DWR coating sheds water in case the day gets rainy. Polyester spacer mesh dumps out excess heat to keep your head comfortably cool. Patagonia also added an adjustable chin strap for security in windy weather, and the dark underside of the bill helps reduce excess glare. No size tag
