Nearly died when I heard the water temp was 9 degrees and howling wind, just before my first ever session at urbnsurf in Melbourne - talk about the acid test for my new radiator wetsuit .
Did a brilliant job- while my feet, hands and face were like blocks of ice after a short time in the water, the rest of me stayed pretty good- meaning I could last the whole session, which not everyone managed due to the icey temp. Also, though warm, the suit wasn't too thick , so still allowed paddling without using more effort - unlike thicker 3/4 suits.
Would highly recommend this suit to any other cold frogs that love the winter surf but not the cold
