Unless you havent been surfing through a winter in the northeast, why is this wetsuit question asked so much? Why is everyone so concerned with what everyone else is doing? If you have a system that works then use it! everybody is different! Im skinny and always cold, so 5/4, hood, boots and mitts are my go to. my friend has a 100 lbs on me and the last sesh was in a 3/2 straight. Water is 53. You guys do the math here.
