The Sherwood Tiga Snorkel is one of the best Dry Snorkels in Diving, and is a Scuba Lab's Tester's Choice Award Winners. The Tiga provides hours of comfortable safe snorkeling. The Tiga's dry valve quickly closes to keep the water out but opens just a quickly to allow fresh air in. And if any water does by chance enter the tube the large reservoir keeps the water away from your breathing and can be quickly expelled through the highly efficient silicone purge valve. The Quick Disconnect Snorkel Keeper connects to your mask in one click.
