You know, Scubapro used to sell drysuits and undergarments. I bought an Arctic II undergarment off eBay several years ago. It's listed as 30° to 35°. It seems to be Polartec 400 plus an outer layer of something. Barbara, I'd sell it to you but I'm afraid I might get talked into diving cold water again soon and it's the bomb.
I've only used it twice - in ABWA with 54° water, and once in JB where it was WAY overkill.
