Yeah dry suits are nice... I used to do commercial diving in canada and drysuits were pretty much mandatory.... it was great being able to get off the boat completely dry ... unless of course my suit leaked and then I made the drive home cold and wet.

Did you get a suit with booties or ankle seals? We used Bare wetsuits during deep/long cave dives in 67 degree water and they were excellent.

Make sure you keep the zipper waxed. There is nothing worse than being stuck in a drysuit.
