Simple and stylish collarless jacket, comfortable to wear thanks to the polyester material. - Brand: nano universe - Size: 38 - Material: 98% Polyester / 2% Polyurethane Thank you for viewing. I used this for one season a few years ago, during my spring commute. It has no lining, making it easy to move in and very useful. There are no stains, but please refrain from purchasing if you are concerned about the wear and tear.
