The Tao Dry is a dry snorkel that allows divers to take every breath with confidence and focus on the reef below not worrying about water in your airway. The top has a Splash Guard and a float mechanism that prevents entry of water when submerged. A generous bore contoured tube provides ample airflow and a lower purge valve enables instant clearing when needed. The snorkel keeper allows attaching the snorkel to the mask strap, avoiding to lose on the surface or during diving. The keeper features a Quick-Release, just push the button to release the snorkel from the mask. Really a great idea and very simple to use. The Tao Dry is designed by Cressi and made in Taiwan. Cressi has been an Italian brand pioneer in scuba diving, snorkeling, and swimming equipment since 1946. The product is covered by a 2-year limited warranty.
