I'm trying to figure out exactly what a Semi-Dry suit is, and how it fits into the "Wet Suit - Dry Suit" discussion. We dive pretty cold water here in Va, and most of the instructors are going Dry Suit but a couple (who I have not been able to catch up with yet) dive the Semi Dry suits. Anyone here have any opinions they'd like to share? I'm looking at likely 20 - 30 dives a year in a quarry/lake.

Thanks all! Chris
