Enjoy your time in the water and breath through your nose instead of your mouth! But only if you have the Ocean Reef ARIA Snorkeling Mask! This full face mask has a large, 180 degree field of vision and a one way air circulation system that keeps the fresh air you need separate from the CO2 exhaled. This helps to prevent fogging as well. A dry snorkel tube stops any water from getting into the mask. It’s available in 3 sizes with wide straps to ensure a snug, comfortable seal. Breath naturally in the water with the ARIA!
