I use a non-crushed neoprene drysuit for all 4 seasons. I am also going diving in the Carribean for a week in July. I plan on diving in a shorty, and rather than rent one, I thought I'd buy one on sale before I go. My question is this - can I use it in the winter as an undergarment with my drysuit? Has anyone tried this? It would be nice to kill 2 birds with one stone......
