Sum, when I bought my firesuit from Diest eight years ago, I went to their shop to be fitted. Unfortunately, I wasn't smart enough to tell the seamstress that I would be driving in a semi-crouch position, having long legs. The result was that when I got belted in, my voice went up about three octives, and I couldn't breathe. I took the pants back and they added to the sides of the legs... what a difference. Anyway, if you measure yourself, go big, or you won't be able to move once you get in.................Fat Bob
