BEWET Full Suit Wetsuit Black Non-zip Fleece Lining XL Size? Custom Order Thank you for viewing. I'm not sure of the exact size as this was given to me. It may be a custom order. I was able to wear it, and I'm 181cm tall with a muscular build, so it seems to be a large size. I don't know much about wetsuits, so please judge from the images. I don't know the thickness in millimeters either. There are some small damages and signs of use, but I think it can still be used. This is a used item, so there may be oversights. I have various other items for sale, so please take a look if you'd like. Thank you.
