Key Advantages

• Unobstructed Field of View: The single-lens design eliminates the bridge obstruction common in dual-lens masks, providing an open, wide-angle sightline.

• True Dry-Top Technology: The upper dry valve automatically closes when surface waves splash over the top or when you submerge, keeping the breathing tube completely dry.

• Ergonomic Jaw Relief: The corrugated lower tube falls away from the mouth when not in use and reduces jaw strain during extended snorkeling sessions.

• Easy Water Clearing: Any stray drops that enter the tube gather in the lower collector reservoir and clear effortlessly through the one-way bottom purge valve.

Tips & Tricks for Prep, Fit & Maintenance

Essential Pre-Dive Lens Prep

• Remove Factory Film: Like all new dive masks, the tempered glass lens is coated with a thin layer of silicone manufacturing film.

• Cleaning Method: Apply a small dab of specialized mask prep cleaner to the inside of the dry lens. Rub thoroughly with your thumb for 2 minutes, then rinse with fresh water. Repeat twice before applying anti-fog spray to prevent fogging.

Checking Mask Fit & Seal

• Dry Fit Test: Place the mask against your face without putting the strap over your head. Inhale gently through your nose. If the mask stays sealed to your face without air leaks, the fit is correct.

• Avoid Over-Tightening: Over-tightening the strap distorts the silicone skirt edge, creating leaks. The mask should seal cleanly through gentle water pressure and light strap tension.

Snorkel Positioning

• Attach the snorkel keeper clip to the left side of your mask strap. Adjust the height of the keeper so the silicone mouthpiece rests naturally in your mouth without pulling on your jaw.

Cleaning & Storage

• Freshwater Flush: Soak both the mask and snorkel in fresh, cool water post-use to flush out salt crystals, sand, and chlorine.

• Check the Dry Valve: Inspect the upper float valve mechanism on the snorkel for trapped sand grains or debris before packing.

• Shaded Drying: Air-dry in the shade. Direct sunlight degrades liquid silicone and weakens plastic frame components over time.
