Everyone fits differently. I recently got a MSS, and although I am almost 250, and a 48 long, I was able to get all zipped up just fine. Go figure, huh.
There is a new MSS set at my local surplus store, I think they wanted $150 for it. I looked it over and bought the used one they had instead, but if anyone wants it, I will gladly go pick it up and ship it to ya for cost.
It could be that the purpose of my life is merely to serve as a warning to others.
