Here is a diving drysuit my uncle lightly used many years ago, but which hasn't seen action in decades. Complete Uni-Suit from Poseidon, with attached hood, mitts, original Carry bag, and manual. It is in fairly good condition overall, considering its age. I think it was a very nice suit for the time.
I couldn't find a tag anywhere in it, but I'd estimate it as a size Large, and should be fine for someone lanky up to 6' tall, as my Uncle was. As seen in the pictures, there is a golf-ball sized hole right in the forehead of the hood. I don't know how it got there, but it might be something you could live with as you're not going to stay dry inside the hood area anyway. Or possibly it could be patched somehow.There's also a small wear spot on a crease in the side of the chest area, I can't say whether or not it can leak through there. I'd think probably not, but I don't know for sure. The suit was put up dry and doesn't have any nasty mustiness to it at all.
