Our RedHead® Outdoor Waterproof Boonie Hat is great for fishing, boating, or light-duty outdoor work. The durable polyester ripstop shell is enhanced with polyurethane to make it waterproof. It also provides UPF 40+ sun protection to safeguard your skin. Polymesh lining comes in handy when a breeze blows through the vents in the crown. These vents, along with the grommets with mesh screens, allow heat to escape to keep you cool and comfortable. The fit adjusts with a quick pull of the bungee cord on the back, ensuring comfort. The 360Á brim, which snaps up on both sides for a cowboy hat look, shades your eyes, ears, and neck from harmful UV rays. The RedHead Outdoor Waterproof Boonie Hat is finished with a cinch cord to keep it in place. Shell: 70% polyester ripstop/30% polyurethane. Lining: 100% polyester mesh. Imported.
