Thank you for viewing. This is a relaxed M size with 3/4 sleeves. The fabric is thick and sturdy. There is a seam down the center of the back (vertically). I've worn it a few times, but there is no noticeable fading or stains. It has been stored in a dark place after washing. #nikoand #nikoand Color: Black系 (Black-based) Pattern/Design: Solid Stains, tears, odors, etc.: None
