Product Information
The Genesis Flow Semi-Dry Snorkel is a flexible, easy to use snorkel built around a profiled splash-guard top that is designed to reduce water intake while snorkeling on the surface, a purge valve in the base for effortless clearing, and a soft, pliable corrugated silicone tube.
Who it is for
This snorkel suits divers and snorkelers who attach a snorkel to a regular scuba or snorkeling mask and want a comfortable setup for extended surface use. The angled mouthpiece is made of 100% hypoallergenic silicone and is soft and supple, and it is replaceable if required, which matters for anyone who wears a snorkel mouthpiece for long stretches.
Key details
- Splash-guard, semi-dry top reduces water entry while snorkeling on the surface.
- One-way purge valve in the base lets unwanted water clear out the bottom of the snorkel rather than through the top of the tube.
- Lower half of the tube is soft, pliable, corrugated silicone that reduces jaw fatigue.
- Angled mouthpiece is 100% hypoallergenic silicone and replaceable if required.
- Snorkel keeper slides up and down the tube so the diver can set the most comfortable position.
- Attaches easily to any regular scuba or snorkeling mask.
Compatibility and sizing
The Flow Snorkel attaches to any regular scuba or snorkeling mask using its snorkel keeper, which permits movement up and down the tube to find a comfortable position. It is offered in three colors: Ultra Violet (FS8700UV), Lemon Yellow (FS8700LY), and White (FS8700WH, the listed MPN).

Frequently Asked Questions
What is the difference between a dry, semi-dry, and classic snorkel?
A classic open-top snorkel is a simple tube, the most reliable design, but it takes on water when a wave passes or you duck under. A semi-dry snorkel adds a splash guard at the top that deflects surface chop, though it still floods if fully submerged. A dry snorkel adds a float-operated valve that closes the top when submerged and keeps the tube mostly dry, at the cost of more moving parts and a little extra bulk and buoyancy.
What does a purge valve on a snorkel do?
A purge valve is a one-way valve in a sump below the mouthpiece that lets water you blow out drain away instead of sitting in the tube. It makes clearing easier, since a short sharp breath clears the snorkel with much less effort. The tradeoff is one more part that can foul with sand or grit, so rinse it and check that it seats cleanly.
How do I attach a snorkel to my mask?
Snorkels attach on the left side of the mask with a keeper that grips the mask strap, leaving your right side clear for the regulator hose. Position it so the mouthpiece reaches your mouth with the tube running alongside your head, without twisting the strap or pulling the mask skirt off its seal. Many keepers are quick-release, so you can remove the snorkel without disassembling the mask.
Do scuba divers need a snorkel?
It depends on your training agency, the dive operation, and the diving you do, since some courses and operators require one. A snorkel lets you breathe at the surface without using tank gas, which matters on a long surface swim or in chop while waiting for the boat. Follow your instructor's or operator's requirements, and consider a folding snorkel if you want one stowed rather than on your mask.
What size or shape of snorkel should I choose?
A snorkel that is too long or too wide increases the volume of air you rebreathe and makes clearing harder, which is why recreational snorkels cluster around similar lengths and bore sizes. A flexible lower section lets the mouthpiece drop away from your face while you are breathing from the regulator. Mouthpiece comfort matters more than any other feature, so pick one you can hold without jaw fatigue.
How do I care for a snorkel?
Rinse the tube, mouthpiece, and purge valve in fresh water after each dive day, then let it drain and dry fully, because standing salt water in the sump grows mold. Check the mouthpiece for splits and the purge valve for trapped grit, both of which are inexpensive to replace. Store it out of direct sun so the silicone stays soft and clear.
What colors does the Genesis Flow Semi-Dry Snorkel come in?
The Flow Snorkel is offered in Ultra Violet (FS8700UV), Lemon Yellow (FS8700LY), and White (FS8700WH).
Is the mouthpiece on the Flow Snorkel replaceable?
Yes. The angled mouthpiece is made of 100% hypoallergenic silicone and is replaceable if required, so a worn or split mouthpiece does not mean replacing the entire snorkel.
What is the Flow Snorkel's tube made of?
The lower half of the tube is soft, supple, pliable corrugated silicone, and the pliable connector tube reduces jaw fatigue during extended use.
How does the purge valve on the Flow Snorkel work?
The Flow Snorkel has a one-way purge valve built into the base of the tube. It creates an easier path for unwanted water to be expelled out the bottom of the snorkel rather than being cleared out through the top of the tube, making clearing effortless.
