I just purchased a Pinnacle Extreme 8mm Semi-Dry Wetsuit. No need for a dry suite with this one.

The ultimate wetsuit, the Extreme blends drysuit and wetsuit technologies to create the warmest and driest wetsuit ever built. A true drysuit zipper and Pinnacle’s unique wrist, ankle, and facial sealing systems allow just enough water to enter to be used as an insulating layer. The Merino™ lining system ensures a warm and comfortable dive, regardless of the environment.
