I would take a look at Pinnacle suits esp the Merino Elastiprene series. I agree with Rich. They are a great suit. I have the 5mm version and was warm in 50 deg water for an hour on a dive. I dove this past weekend with it in 45 deg water for almost an hour and was chilled not freezing cold while the other divers were shivering. I can only imagine how warm the 7mm version is. The seals are very nice and the 10mm spine pad is also nice.
