There are size charts at. That indicate that size its heights between 60 and 64; Weight 91-114Kg. Ive also worn it when I was lighter (down to about 82kg) and it was fine if a little baggy. Because of the stretchy construction it will fit a range of sizes and shapes comfortably.
This example is in good condition, and has always been well looked after. Its been modified slightly: a hole has been made in the outer layer of the left leg, to allow a p-valve tube to be routed through it. Given the multi-layered construction though, it doesnt mean you have a bare spot on the leg (see pictures for more details). In use you wouldnt notice it at all.
