Rash wetsuit inner, size M. I wore this under a 3mm fullsuit, with boots, and used it in Chiba South and further south during the daytime in mid-winter. Paddling was easier, and it was warm. It shows signs of use, but there are no issues with its functionality. I'm selling it because I bought a better wetsuit. I think it cost around 16,000 yen. New ones are often expensive, so how about this one? There are no major tears, scratches, or stains. Please understand that this is a used item. Thank you.
