The 3D Flex Dry Snorkel is the original dry snorkel. The unique floating valve system that closes on contact with water is the heart of this dry snorkel. When you see something on the bottom you want to get a closer look at using a conventional snorkel once you submerge your snorkel tube floods with water. Not so with the 3D Dry Snorkel. The float prevents water from entering the snorkel tube keeping it dry for your return to the surface. Nothing else compares with the dryness of this specially designed snorkel. Once you have returned to the surface the float falls away from the tube opening allowing water free breathing again. You won’t need to blast” the water out like with other snorkels, just breathe in and you good to go. Snorkel is designed for comfort with its patented adjustable mouthpiece section with dual ball joint for a custom fit. The snorkel is also equipped with a one-way purge valve at the bottom of the snorkel which allows any residual water to drain out as you breathe easy. The M-Line Snorkel 3D Dry with its drop-away corrugated lower section makes it ideal for Scuba. The mouthpiece section will fall away from the face and will not interfere with the Scuba regulator second stage when switching from the snorkel to the regulator. Snorkel mouthpiece is made from high quality silicone rubber for added comfort. If you tend to chew on your snorkel mouthpiece not to worry the mouthpiece is replaceable. Snorkel come equipped with XS Scuba’s quick-release snorkel keeper with push button action. The M-Line Snorkel 3D Dry is available in multiple color choices.
