The finishing touch to any wet weather walking outfit, the Outdoor Research Halo Waterproof Sombrero Hat features a fully waterproof design with taped seams for that extra reassurance that not one drop of rain is going to make its way through. While the hat’s breathable design, mesh lining & vent to the back will all put a stop to sweat, keeping you cool, dry & comfortable. Magnets on the brim & the dome of the hat let you fold up the sides for better visibility when the weather clears. While a drawcord adjustment ensures the perfect fit.
