Thank you for viewing. 2023AW Uniqlo x White Mountaineering Fleece Full-Zip Parka (Long Sleeve) Black Size M This is the M size, which was the least available size. The S size was a bit small, and the L size was a bit large, so I think many people will find the M size to be a perfect fit. Popular sizes sell out quickly, so I think the M size is rare. Even though it's size M, it felt like you could wear something a little thick underneath, so it's the best size. I will not respond to questions or various requests after purchase, so please ask before purchasing. I will pack it compactly, so I will not accommodate packing requests. Also, please note that there may be some creases from folding.
