The with "does not stop" is meant literally, because after two applications of the suit is torn at the lower back at the base of the zipper. "A round hole", to quote one of the predecessors. Apart from that, the suit is never 3mm thick in life, at most places. I have another 3mm shorty and is noticeably thicker than this one. I would say a maximum of 2.5 mm, here and there even thinner (eg collar could be 1mm).
