The new full face masks may be related to a disproportionate number of deaths, possibly due to buildup of CO2. Snorkel Bob's won't even carry them. There's no proof, but just something to consider.

That's interesting - thanks. I'll stick to my mask and snorkel.

It's not the brand, but the style; evidently the mask allows for CO2 buildup. I read about it in West Hawaii Today (easily found in a search) . I agree, they look cumbersome and uncomfortable, and I've seen too many people emerge sputtering and trying to adjust them . But maybe that's just the fit on someone who's not accustomed?

Yoiks, just searched for "full face snorkel death" and other keywords; I'm sticking with my mask and snorkel, too!
