The movable float design effectively prevents water from flowing into the top and prevents water from entering the snorkel to prevent choking, allowing you to snorkel, dive, or swim ly. 2. Leakproof and antifog design The nose mask is made of liquid silicone, which perfectly adapts to various face shapes and maintains a high standard of leakproofness and comfort.
