Pivot Dry Technology for your snorkel. The patented Pivot Dry Snorkel has a top that closes to seal out water when you go underwater. While snorkeling on the surface of the water, just breathe normally. When you want to dive under the water, take a deep breath and then submerge. The snorkel will automatically close and seal out the water from the tube. When you resurface, just exhale and breathe normally. [MUSIC PLAYING] Unlike most dry snorkels, the unique design of the pivot top also provides a large open tube for easy breathing while on the surface. Yet, it keeps out all water. [MUSIC PLAYING]
