Thank you very much for viewing this product out of the many available. This is a niko and ... black nylon jacket (windbreaker). I have worn it a few times since I bought it. I think it can still be used. The size is listed as 4, but it fit me perfectly, and I usually wear a size L. The size is as follows, although this is amateur measurement: Shoulder width: 53cm Length: 72cm Sleeve length: 82cm I plan to ship it compressed via Yu-Packet Post. I hope someone who can wear it stylishly will buy it. Thank you.
