Size is Men's M. (This product is made to overseas standards, so it is equivalent to a Japanese size L) I am 177CM and 65-70kg, and it was a perfect fit. Worn 3 times. After use, it was washed with wet shampoo & softener and stored indoors. It was very useful in spring and autumn. Since it was only used for wing foiling and SUP, there is no wax residue. The article is clean. 3mm2mm I think it's a beautiful item with few times worn, but Please understand that it is a used item before purchasing.
