I bought one of these suits off of Ebay for a reasonable price. Its fits me well, I am 5'11" and 200lbs. (lil bit o' chunk around the middle) The material is thin, but it gives me piece of mind when I wear it. The elastic is nice and snug around the bottom and when I wear my gloves I feel I am well protected.
Just a short review in case anyone has been thinking of ordering one.
