Thank you for viewing. Used RLM wetsuit full suit. I believe the thickness is 3mm, but I don't remember exactly. I ordered it several years ago. I think it's probably a M to ML size if it were off-the-rack. I am 165cm tall and weigh about 60kg, with broad shoulders and a slightly muscular build. - The rubber feels a bit stiff. - There are some frays and tears on the cuffs of both hands and legs. - There are stains from wax, sunscreen, and Vaseline on the surface. - Some parts of the seams are separating, so water leaks in a little, but I haven't been able to pinpoint the location. - Some of the tape is peeling off. It's not in good condition, but how about it for those who want to buy it cheap or for a second suit? Please refrain from purchasing if you are sensitive to used items. I will fold it up small and ship it. Thank you for your understanding. Thank you.
