PETER S I am not familiar with the ocean reef as I dive with an interspiro full face, I use this hood with both dri suit and wet suit. It is the most comfortable hood I have ever owned. It is also first hood that seals perfect on the mask without air leaks. Hope this helps.....Pete

TRENT S I dive with a AGA Interspiro FFM. The hood does a great job of making a tight seal with the mask. The hood is designed to be used with a drysuit do to the lack off a bib. My guess is that you will get water movement around your neck and shoulders because you can't tuck it in. Depending on the temperature of the water you are diving in, that could be pretty unpleasant. As you probably know, hoods for FFM are few and far in between. Another option is trim the face opening of a bib hood to fit your FFM. Not a perfect option but it works.

ELIZABETH R I use a dry suit but this hood has worked very well for myself and a couple other members of my dive team.

Kris R Hmmm looking for something for a full face mask but doesnt seam to be much choice out there ? Im gussing theres no vent hole in the top which is an easy fic,

MARK A Kris, I'm not sure I'd recommend the Seasoft Pro. Here's the problem. I bought it to use under an Auga mask, but the hood doesn't fit that snug against my face. So when the Auga mask seals to the hood, exhaled air goes between my face and the hood, filling the hood with air. After a few dives looking like Megamind, I finally ended up trimming the hood to fit up to but outside the Auga mask. I'd recommend either getting a different hood with a tighter seal against your skin, or get a Seasoft mast that fits really snug. Having said that, I usually wear a XXL hood, which Seasoft didn't have. I ordered an XL.
