The SURI Snorkel by Sherwood is a cost effective regular tube snorkel design. The SURI Snorkel Tube is contoured for hydrodynamic when surface swimming you'll forget it even there. The corrugated flex tube and removable, replaceable mouthpiece is made from 100% high quality silicone for comfort and fit. The corrugated flex tube design lets the mouthpiece swing away from your mouth which makes it great for Scuba. If water enters the breathing tube the deep reservoir below the mouthpiece with one-way purge valve will keep the mouthpiece dry for easy breathing. The SURI Snorkel is equipped with a quick disconnect snorkel keeper and is available in multiple colors.
