I'm going to bump this just for New People .. Like me. Slipstream II suits run small. I'm 5' 10 180 pounds and from my shoulders to my groin is a little on the short side .. I bought one for my wife and she would not fit in the suggested size suit. The suit she needed says it will fit a person up to 155 pounds .. I dare you to tell my wife she weighs 155 pounds .. If you are on the upper 1/3 of the size chart go to the next size. I'm lucky .. my wife can sew anything .. She's fixing mine ... JUST FYI.
