Best of Japanese Classics - Size: Approximately M - Color: Black - Material: Neoprene - Zipper: YKK Thank you for viewing. There is some wear and tear, but the fabric is soft and I think it can still be used. Please refrain from purchasing if you are nervous as this is a used item. ※ I just purchased this on the same site, but the size doesn't fit me, so I am selling it. For reference, I am 170cm tall and weigh 67kg. I usually wear ML for vests (without zippers), springs, and seagull suits. This product, perhaps because it has a front zipper, did not close on me due to my chest size. I purchased it as ML, but there is no size notation on the product, so I can't say for sure, but I think it's about M. Thank you.
