Rebreather World - View Single Post - Long, deep, wet dives in 20-21c ??

Personally, I know I won't be able to dive for 3 hours in 20C without feeling cold wearing 7mm (i.e. not in Red Sea, but close)

Lately, I have been diving around 2.5 hours with 5mm but only the bottom was around 18-20C (max BT 42 mins) and majority of the deco was in ~25C.
And I was cold at the end - not trembling cold, but ready to get out of the water cold.

Even if your drysuit is leaking a little, it won't feel as cold since only spots of your body is slightly damped from the wet undersuit - versus the entire body is wet in a 7mm wetsuit.

Then again, I am more suspectible to cold than most people...
