The Sphera is supposed to come with an anti-fog coating- that wears off eventually. I wonder if that was the film layer that you were talking about?
My Marina has given me zero problems with fogging so far- best of any mask I've used, except for the sphera, in this regard. I've owned my Alien for a couple of years and it STILL fogs up on me quite a bit- and I've cleaned it many, many, many times. There must be something in the green silicone that causes this????
The plastic lens on the Sphera seems to distort things the same way as an AGA (full-face mask) does. Everything is clear- just different.
Maybe we can petition Technisub to keep this mask in their line-up?
