Semi-dry style snorkel great for snorkeling. More forgiving than an open-ended snorkel when diving underwater as it allows some water to enter the tube but not as quickly. Quick-release snorkel keeper makes it easy to clip the snorkel to your mask strap.
Mouthpiece: Soft silicone
Flexible Tube: Yes
Purge Valve: One at mouthpiece and one near the top of the tube
Snorkel Top: Semi-dry
Works like a charm. Easy to clear and rarely filled with a ton of seawater.
