Thanks to all who have replied so far. I will be checking out your suggestions.
Here are some more details. I have successfully used a Kirby Morgan Exo hood with a FFM (mostly an AGA). The hood is designed for this purpose with neoprene skin inside and out for mask sealing. I have seen another make, maybe pinnacle or otter but not sure, that looked good. I also use this kind of neoprene hood under a latex hood on a vulcanized suit for public safety diving since I'm a "belt and suspenders" kind of guy and really dont rely on the fleece hood under the latex hood to remain dry throughout the day.
It is my choice to seal the mask on the outside of the hood for warmth and to a lesser extent to reduce possible hazmat exposure to fuel, etc. Also, I am blessed with a narrow face and the hood fills it out for a surrer seal. Yesthis is a personal problem. I'm just looking for any leads on manufacturers already producing such a hood for a good price.
Someday in the not too distant future we will all be heading to the Scuba Department at the local Wallmart.
Thanks,
