About IST 3D Flex Dry Snorkel

While we don't claim to have "re-invented" the snorkel, the 3D FLEX DRY is pretty close to it!

3D FLEX DRY's special top has not 1 but 4 valves, each capable of blocking the air entrance independently. If the snorkeler unintentionally submerges the top part of the snorkel (i.e. looking from side to side), a conventional dry snorkel will have its only air passage closed off completely as soon as it senses buoyancy change but in the same situation with aSN201 snorkel, only the valves that are underwater will shut while the others will remain open, providing unobstructed breathing path.

Apart from the special quad-valved dry top and double-jointed bottom section, SN201 is also equipped with a large purge valve and swiveling snorkel keeper.

User comfort is guaranteed with 2 patented 360? swivel joints. The ball-joint style connections can be found just below the mouthpiece and the purge body. Both can be freely rotated to suit each individual's facial profile and mask set-up preferences, whereas a traditional stiff tube has very few or no ways of making adjustments, resulting in discomfort and reduced snorkeling enjoyment.

DIVE PINK & FIGHT BREST CANCER! For every Pink Snorkel $3 will be donated to fight breast cancer.
