Hats are just a necessary part of diving. More often than not, the dive location is sunny with little shade, so divers need something to keep the sun out of their eyes. Or, you just climbed out of the water, and that temporary warmth you had is quickly fading in the wind. Get your suit hood off and wrap your head in the most comfortable beanie you've ever dropped on your head.
All our diver hats are purpose-built with the diver in mind.
