I normally don't write reviews, but this is one of the rare product that I highly recommend to everyone. This is hands-down, the best snorkel mask. I went on a trip to St. Kitts and Nevis. The mask was more than I expected. It was easy to slide on, easy to breathe normally, view of the ocean corals were amazing, and even my makeup was not ruined! Even my boyfriend was extremely impressed with the mask. I was about to surprise him with the Seaview Snorkel Mask as a gift, but the company has offered one as a gift that fits his size. That is amazing customer service! I can't wait to use this mask again when I fly out to Zanzibar!I only wish that there is a similar mask for scuba diving.
