Cressi Neoprene Mask Strap Cover The Mask Strap Cover is the best solution to help to hold the snorkeling mask on your head. Won't pull or tangle hair. The hair tends to stick to the silicone and the strap can pull the hair and it's annoying. Soft neoprene strap increased comfort. The Neoprene slips better on the hair, and the large surface adjusts to the shape of the back of the head, holding the mask in place. Won't shift on mask strap: there are Velcro tabs inside the cover to anchor it to your silicone mask strap. Elastic sewn edge tape reinforced. The product is designed by Cress and made in China. Cress is an Italian brand pioneer in scuba diving, snorkeling and swimming equipment.
