This is a SHIMANO jacket purchased from a sports shop. I used it for cycling in the winter mountains and for leisurely cycling around town. If you wear Heattech underneath, you can cycle comfortably even in mid-winter without feeling cold. The material on the back of the jacket is distinctive. I am selling it because I no longer have the opportunity to use it. Size: XL (LL) The fit is tight. Feels like a size L. Number of times worn: About 5 times outdoors.
