That might be part of your problem. Multi use where your needs will be different in different uses. If you size it for a hood it isn't going to fit very well without a hood. Add in issues of air entrapment and venting, padding/suspension. You really should plan on a helmet just for diving, and a different one for the other uses.Yeah, if I find one that might help. I am hoping to find an actually impact rated helmet w/o foam. Not that an impact rating would be needed just for diving, but it would be multi use... Anyway finding new, un-used suspension mount no-foam climbing helmets... I may be strange, but I hesitate buying such a helmet used, not knowing where it's been and what it was exposed too... will keep looking so.
The padding/impact rating needs in water are going to be different than in air. You just don't get the speeds in the water. You get a bump, not an impact. Rocks fall slow, you move slow, actions are much more muted in the water.
