This is an RZST reversible zip hoodie. It's a brand famous for supporting metalcore and EMO bands like AVENGED SEVENFOLD and EIGHTEEN VISIONS. Size M (no tags or other markings), one side is satin fabric with Japanese-style embroidery, giving it a sukajan-like feel. I recall the zipper pull decoration was a Hanzōro design. Width approx. 50cm, length approx. 67cm.
