FINIS Snorkel Dry Top Designed specifically for the FINIS Original Swimmer's Snorkel (adult and Jr) and the FINIS Glide Snorkel. Uses a patented design to keep the inner tube of the snorkel dry. An internal buoy rises when submerged to keep the snorkel dry, and falls when out of the water to allow for easy breathing. Water stays out of snorkel during swimming and turns.
