The Waterman Hat exceeds all our requirements for a product. It is simple, stylish and amazingly functional. We use this hat surfing, kite boarding, and paddle boarding. Having a hat to shield your eyes from the sun extends your time on the water. Staring out onto the horizon looking for waves is blinding. To the surprise of many people the hat stays on even when ducking under a wave or kite surfing in 30+ mph winds. No need to worry if the hat does come off your head as it floats. Made with a polyester foam front and nylon mesh back it is super durable and easy to clean. Simply rinse it with water and the sweat, dirt and salt water wash away. Just as importantly it dries fast. With a snap style back the hat is one size fits most.
