A full wetsuit would be a better bet.
Insulation and floatation built in

I don't know for sure what kind of suits they wear if the ship sinks on the TV
series, "Dangerous Catch" (I think they are dry suits) but they had a guy tell
about surviving in the water for well over 24 hours, in the Bearing Sea.

His partner was in the same situation, and she did not survive.

So I guess the moral of the story is that a survival suit can help you survive
in cold water for a pretty good time, hopefully until you are rescued alive.
