Ideal for novices and experienced snorkelers alike, this mask/snorkel combo enables natural breathing through either your nose or mouth. Visibility is excellent, due to the ultra-wide field of view. Unlike diving with a separate mask and snorkel, the integral snorkel of the Sea Vu FFM is oriented at the optimum angle, which along with the “dry top” design, virtually eliminates the distressing entry of water—making the Sea Vu FFM a great choice for first-time explorers of the underwater world.
