I purchased this mask from a local dive shop in Kona. I used it for the first time today. I love the fit for my face type. It is super comfortable and did not fog up at all. The only issue I had was that when free diving to a depth of about 40', the air in the mask had compressed and I had to exhale in to the mask to alleviate the "face squeeze." I am an amateur self-taught free diver and while I have heard of this before, I had not previously experienced this with my Aqualung Sphera mask. So that took some getting used to. But so far my first impression is a favorable one, and I look forward to many more successful dives (and classes) in the future! And I like that it makes me look like Batman.
