The Patagonia Surf Brim Hat protects you against the ruthless sun and stays securely on your head when you're on your surfboard, SUP, or boat. The hat's quick-drying and water-repellent nylon fabric and neoprene chin strap and headband are made to withstand splashing water, light rain, and dunks under the waves. The full brim offers 360 degrees of shade and UPF 50+ rated sun protection, and the soft, adjustable chin strap and headband ensure the hat stays comfortably and securely on your head.
