Also has a go pro mount so you can attache a camera to it so your hands are kept free i am very happy with the quality and how it works breathe easy under water with out getting mouthfuls of water i have bought several snorkel sets before and this is the best one so far

This is a really good professional seaview diving mask i am very happy that it fits very secure but still feels comfortable when wearing the lens are shaped so that you get the full view of everything you are looking at under water without having to keep moving your head all around the lens are very big and the nose piece sits great on your face so no water seeps in when using it is also anti fog tempered glass ans did work great after getting out of the water with them on did not have to wipe them off to see
