This mid-profile cap is made with a blend of cotton and nylon mesh, so it's both breathable and durable. The pre-curved visor will keep the sun off your face when you're out fishing or working on your boat, and the adjustable snapback closure means you can adjust it to fit your head shape just right. The cotton sweatband helps keep sweat from dripping into your eyes, so you can stay focused on what matters: catching fish (or whatever else you're doing).
