Well, from the looks of the mask your asking about, it almost looks identical to the one I have, but mine is a Oceanic Shadow. Here's what the one you want looks like, then mine:
^^^ Atomic Frameless
^^^ Oceanic Shadow
------------
Now, both are frameless, but I've never used the Atomic version. Althought, I love my Oceanic Shadow. Never leaks! You do have to clean it alot the first week or so you own it. The only defog I've found that actually works is 500 psi, or spit. It's also low profile, so you get a very nice field of view.
Hope this helps, even though it's not answering the exact question you had
