Comments about Genesis Genesis SM7400 Quadra Mask:
I was initially attracted to this particular mask because it attempted to provide low volumes with a large range of vision.
It delivered.
Fit was great. The mask seals extremely well to the point where I don't need to clear it at all during most of my dives.
As far as fogging, as long as the the lenses are made of tempered glass, I've never had fogging problems with any mask, irrespective of brand. Polycarbonate lenses found in "toy" masks are another story. As long as you clean the temperate glass lens with tooth paste right after receiving a factory new mask, plenty of plain spit before a dive will cure any fogging. Never had any problems at all with fogging with this mask.
