Snorkeling Supplies Full Dry Diving Mask Snorkeling Full Cover Swimming Mask Adult And Children's Swimming Masks There are floating beads inside the stop valve of the breathing tube. When fully submerged underwater, the buoyancy of the water lifts the floating beads to block the air inlet hole. It can prevent water from flowing back in, and at the same time, it cannot take in air. After the breathing tube is exposed above the water surface, the floating beads descend and the air intake hole opens. If water enters the mask, you can lower your head after the water comes out and gather the water inside at the mouth of the mask. The water will be automatically discharged and there is no need to remove the mask for cleaning Product Information The set includes: Mask *1, breathing tube *1, silicone ring *1, nut *1, pair of earplugs The silicone ring is used at the interface between the mask and the breathing tube.
