Enjoy snorkeling with a full face snorkeling mask that allows you to breath through your mouth and nose in a more natural way. No more jaw fatigue from biting down on a snorkel mouthpiece. Features an unobstructed 180° field of vision and an anti-fog window. The snorkel has a mechanism that plugs the top of the snorkel when immersed in water, ensuring a dry snorkeling experience. Not recommended for freediving.
