I have a 7mm uncompressed neoprene drysuit by Poseidon, with built-in hood. Also a older-style dump (chest dump), as well as a crotch zipper. Zipper looks like it's seen better days but also seems like it would not leak. This guy is in rough shape and is sold as-is. Would fit 5'9-5'11" I'd guess.
$35+shipping, as-is.
