I would get a trilam dry suit.
Who wants to be WET when they go scuba diving-ick!
You can dive a trilam in 48 degree water and 70 degree. I saw some guys in North Carolina diving dry suits and the water was 70 degrees. Towards the end of my dive-as I shook with hypothermia uncontolably on the safety stop in my hooded 5/4 wetsuit -I was looking at those dry guys thinking "So smart, so smart indeed". I had thermal envy.
if you have the money SKIP, PASS, DO NOT STOP, AVOID a heavy wetsuit. They are a relic-a thing of the past. If you try dry diving you will never go back to wet-unless the waters warm like where Im going next week-Cozumel for 8 days and 7 wonderful nights of some of the greatest diving on earth!!!!!!!!!!!!
Seriously, a trilam suit can be worn in 32 degree water to 70 degree water depending upon the undersuit-or no undersuit. It's the best way to go. Save your money a get a dry suit. You will thank me for all eternity.
Bob3 on this board sells the Viking Extreme and that's a great trilam suit at a great price.
