Provides warmth
Heat from your head is partially retained by the Neoprene. Its 3 mm thickness and stitched and glued seams mean you can keep on surfing - and keep cold and fatigue away longer. The benefits of this stitch-bonded cap are quickly seen in its capacity to keep cold water out, as compared to a regular stitched cap.
It will delight you for windsurfing, surfing, sailing even along the coast!
Quality of hearing when surfing
This cap has holes on both sides to allow you to hear what's happening around you while keep heat in and water out of your ears. This allows for better awareness of your immediate surroundings, letting you better hear other surfers as well as the elements (wind, waves, etc.).
