NRS has a great staff of people that use their products. They were able to fit me over the phone. I'm 5'8", and only weigh 135. It has been hard for me to find a suit in the past, but they were great. Plus they have major deals right now! Much less than I thought! I suggest a Farmer John and a jacket. I wear the farmer almost all season in Buzzards Bay Mass. and the jacket too, May thru June, and September thru October. Sail safely. Brian
