If you want to be able to go surfing in the coldest of days a 6mm wetsuit is an absolute session saver. When wearing a 6mm wetsuit cold is never a reason to not go. Of course it has to be combined with a good pair of neoprene boots and neoprene gloves otherwise it is not going to be warm anyway. 6mm wetsuits are made for winter, some people are always cold and in this case the 6mm is a great option too.
