When/if you abandon this endeavor, get an Aqualung lip guard to add to your existing regulator for cold water use.Yep, you are so right. What I'm looking at is a toy novelty. But I see potential uses for my other activities; when dredging for gold my lips get really cold from the river in 3-6ft of depth. If this toy FF mask fails I'll try out the IST M37 FF mask $90-130, it's been around for decades.
