No Leakage: The professional diving mask should be made of liquid silicone. The skirt side of the diving mask adopts food-grade liquid silicone and double-layer leak-proof design, which can prevent leakage and not compress the face even when scuba diving. The soft silicone frame fits a wide variety of adults and youth. One-Piece Lens Design: One-piece lens reduces visual obstruction and maximizes our vision underwater. Whether you are snorkeling, snorkeling, swimming, spearfishing or other water sports, you would be happy because of the excellent visual performance. Tempered Glasses Lens for SAFE DIVING: Chose the shatterproof ultra-clear tempered glass to withstand the pressure of deep waters for all types of diving or swimming. At the same time, the goggle snorkel mask is scratch resistant and always provides a clearer view underwater. Sleek and stylish: The snorkel mask has a modern, sleek design with a black finish cool to bring you a high-end fashion style to stand out from the crowd. The black silicone can also prevent lens glare (reflection off the lens) to reduce visual disturbance. Easy adjustment strap: The snorkeling mask for adults has a strap adjustable silicone head, making the mask suitable for all adult face types. Our snorkel mask is a great gift for men and women who love snorkeling.
