The fabric is a special made-in-Japan material knitted by Okazaki Knit in Wakayama, specifically for the six style. The yarn used on the front side is recycled cotton, and the back yarn is a sustainable material using unbleached natural color without dyes. The back side has a fine, smooth, and comfortable brushed fleece that feels great against the skin. It's a warm material despite being lightweight. Purchased from ZOZOTOWN, the tags have been removed, but it has only been tried on. I'm selling it because I haven't had a chance to wear it. Please understand that it has been stored at home. Immediate purchase is welcome. The original price was 18,590 yen. Size M Width 54cm, Length 63cm, Sleeve length 83cm Slightly larger than a standard M size.
