Top-Notch Technology

The IST SN-204 features convenient details with divers in mind. An exterior splash guard covers the top of the tube to keep water out when buoyant at the surface, while a specially-engineered hinge system and float seal the tube when underwater.  This updated model prevents the airway from becoming unintentionally blocked at the water's surface.

Comfortable Fit

A soft, malleable silicone mouthpiece is hypoallergenic and forms to your bite for reduced neck and jaw fatigue. The flexible corrugated tube is ideal for switching to a regulator as it falls away from the face when not in use.

Versatile Use

Ideal for both scuba diving and snorkeling, the SN-204 provides everything you need to have fun in the water. Available in 5 different sport styles, you can explore stunning reefs, encounter wildlife and venture deeper into the unknown with a quality snorkel that's fit for you.
