Full Face Snorkel Mask for Adults - CO2 Safe Valve, Wide View

Our review of this full face snorkel mask finds it best for recreational snorkelers who want a wide field of view and an easier, more natural breathing experience. The single biggest reason to consider it is the CO2 safe valve system developed to DIN standards in Germany, which reduces the risk of rebreathing exhaled air and the headaches that can follow. It fits American face shapes with added silicone for a secure seal and comes in two sizes so older children and adults can get a comfortable fit.

Key Features

• CO2 safe valve: An intelligent valve system separates fresh intake from exhaled air to prevent dangerous pendulum breathing for safer snorkels.
• 3x larger snorkel intake: The snorkel admits three times the air intake area compared with many competitor masks, making breathing feel easier and less restricted.
• German development and testing: Designed and tested to DIN 136 standards in Germany, offering stricter safety oversight than many basic snorkel masks.
• Full face design: The whole-face lens provides a wide viewing angle and clear field of vision for relaxed surface snorkeling without the traditional separate snorkel and goggles.
• Comfortable silicone skirt: Extra silicone around the face improves the seal for American face shapes and enhances long-session comfort.
• Two sizes including S/M: Available in two sizes so snorkelers from about 10 years old (S/M) to adults can find a better fit.

Who It's For

This mask is aimed at leisure snorkelers, families, and beginners who value effortless breathing through mouth and nose and want a panoramic view while exploring shallow reefs and calm bays. It is also a good choice for snorkelers who prefer a secure, comfortable seal thanks to the increased silicone around the face.

It is less suited for deep freediving or technical diving where a traditional low-volume mask and separate regulator or snorkel remain standard. Those who need a perfect watertight fit in rough surf or who prioritize managing very aggressive leaks should consider alternate gear.
