Just out of curiosity, has anyone here been too hot during a dive, ever? What were you wearing and what was the water temperature? Any other factors (exertion, heated undersuit)?

I'm wondering if the reason not to choose the warmest possible undersuit all the time has more to do with convenience/travelling light, overheating on the surface pre/post dive, and not wanting to deal with more suit gas than you really need to. Even dived fairly tight with not much gas in it, I guess a 400g undersuit traps a bit more gas than something thinner, and takes a little bit more effort to vent during ascents.

Other than all those things, I'm interested to know if there's such a thing as being too hot on a dive?
