Review on Greatever Snorkel Mask: Explore the Underwater World with Foldable Panoramic View and Detachable Camera Mount for Adults & Kids by Terry Wilson

Bought this for a trip to Hawaii and used it on the Big Island and Maui. While it's a little difficult to get the air portion to rise, it's easy to just place the mask on your face once you've done that. You can't put a hose in your mouth - just put your face in the water and breathe. It will probably take up a little more room in your suitcase than a traditional snorkel mask, but not too bad. I had no problems with water getting into the mask. It seems that more and more people are using this type of snorkel mask.
