Hello all, has anyone tried acclimatising to cold water so that they can use a thinner suit? I will be in the market for a suit soon and would rather use a 3 or 3.5mm than a 5 if I can get away with it. I have been going out in a normal surfing suit for a few weeks and I do seem to be getting longer times in the water before I have to get out. The first time was not too good, had uncontrolled tremors in the legs and the exhaustion didn't creep up on me, I was ok, then I was weak! Anyway learnt that lesson and took it slowly, slowly. Just interested if anyone has tried this and if so, how did it go? Swimmers do it so I cant see why it shouldn't work for divers. I just prefer the feeling of thinner neoprene Anyway thanks in advance for any info.
