The size is listed as 30, which likely corresponds to a size L. There are two zippers on each leg, allowing you to adjust the width. The zippers are YKK and operate smoothly. More details can be found at the following URL (although the size is different): https://www.trefac.jp/smartphone/store/1034013417349039/c2907745/ Waist: 42cm Inseam: 73cm Thigh width: 25cm Leg opening: 27.5cm (when the leg zippers are closed) Please note that these measurements are approximate due to amateur measuring. I am 175cm tall and of slim build, and this was a perfect fit for me. Feel free to comment if you have any questions or would like to negotiate the price.
