I picked this suit up tonight and did a night dive at the local quarry. I dove for 45 minutes in 60 degree water and I was super-toasty. Honest to goodness, I had way more flexibility in the Pinnacle 5mil than I do in my other 2mil full suit. The warmth was awesome, way more than I would expect from a 5mil. I think this suit would be very comfortable in the low 50's with a hood/gloves. Absolutely great suit, would definitely recommend it. Not to mention it is pretty stylish. I mean, what's the point of being warm if you don't look good?
