Buying used is definitly a risk I wont argue with that. I will be upfront and say I am 6'2" 200lbs and have a size 34 waist. I dived this in a drysuit with thick undergarments. Although I did trim the webbing I always plan on selling my gear down the road and left it large enough for somebody bigger than me. If you buy it and I am wrong I will give you a refund. They are bothva size Large so dont think it will fit like an XXL.
