Seaview 180 Full-Face Snorkel Mask V3 for Adults — 180° Panoramic View, Flowtech Breathing

The Seaview 180 V3 is a full-face snorkel mask that delivers a wide 180° view, continuous fresh-air circulation, and a comfortable, leak-resistant fit for adult snorkelers.

Built from iterative design and third-party testing in the United States, the V3 combines a large panoramic lens, an improved Flowtech breathing system, and three adult sizes to give clearer vision, easier breathing, and safer performance than earlier full-face masks. It includes an adjustable GoPro-compatible mount and features meant to reduce fog and water intrusion so you can focus on the underwater scenery.

How does the Flowtech breathing system affect comfort and air circulation?

The V3’s Flowtech system separates inhaled and exhaled air into two chambers and uses four intake valves plus one-way outlets to encourage steady airflow. This lowers breathing resistance and keeps fresh air moving through the mask, reducing stale-air buildup and minimizing fog.

• Two-chamber airflow separates inhale/exhale paths for clearer air.
• Four intake valves optimize fresh air delivery on each breath.
• One-way valves direct exhale away from the viewing pane to reduce fogging.
• Third-party airflow measurements guided design improvements.

What makes the Seaview 180 V3 safer and better tested than basic masks?

The V3 was developed by experienced product engineers and refined through prototyping and external testing to validate airflow and CO2 performance. Designers focused on fit, visibility, and secure breathing to meet recreational snorkeling needs without claiming medical benefits.

• Engineered and iterated in the USA with attention to airflow dynamics.
• Third-party experts measured airflow and CO2 metrics during development.
• Redesigned snorkel placement improves head movement and stays above water more reliably.
• Ergonomic shape reduces leaks and improves overall comfort in water.

How should I choose the right size and test fit before using it in open water?

V3 comes in three adult sizes to provide a closer, more secure seal than two-size alternatives. Measure from the bridge of your nose (between the eyes) along the side of your nose to the tip of your chin to select a size; if you’re between sizes, the smaller option usually fits better.

• Measure from bridge of nose to tip of chin along the side of the nose.
• Refer to the included sizing chart; choose smaller size if between sizes.
• Always test the mask in a pool to confirm seal and breathing before open-water use.
• Check straps and fit adjustments for a snug, comfortable seal.

What practical features help with visibility, recording, and leak control?

The mask’s 20% larger panoramic lens gives a wide field of view for snorkeling, while anti-fog airflow and an ergonomic skirt reduce water intrusion. The swivel GoPro mount is positioned near the chin to keep the camera submerged and offer better footage angles.

• 180° panoramic lens increases underwater visibility and situational awareness.
• Continuous fresh-air circulation helps keep the lens clear of fog.
• Ergonomic skirt and seal minimize leaks for more time in the water.
• Swiveling GoPro-compatible mount lets you capture hands-free footage easily.

Who should consider the Seaview 180 V3? Recreational snorkelers and adults seeking a comfortable, wide-view full-face mask with improved airflow and a camera mount will benefit most. It’s designed for swimmers who prefer natural nose-and-mouth breathing, want clearer panoramic views, and value a tested, ergonomic fit. Be sure to size the mask carefully and trial it in shallow water before extended snorkeling outings.
