Perfect for warm days, the Sail Hat has UPF 50+ sun protection as well as a Hydrofil sweatband to wick any moisture away from your skin. The grommets will provide ventilation at the side of the hat. If you\'re out by the coast then be sure to use the wind cords to keep your hat secure, don\'t work if it does go in the water though as it is buoyant so it will float.UPF 50+ Sun protectionWater repellentBuoyantFront and back wind cordsMildew resistantHydrofil sweatband for moisture wickingVentilation grommetsSnap up brim
