Very cold water diving is done in a dry suit, which has seals around the wrists and neck that prevent water from entering at all. Well, it may get damp.
Typically, these suits are made of a thin material and one wears insulation beneath. They do make crushed neoprene versions, but the insulation just gets lighter.

Water will conduct heat off your body at an incredible rate, so just staying dry has a huge impact. However, for any length of time, one needs insulation as well.

They do make immersion suits with these same dry seals, but they must be trimmed to fit your specific neck and/or wrist size or they will either choke you or leak. That's why you don't find them as generic suits.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
