Waxed Coating Track JacketDESCRIPTION 11 by Boris Bidjan Saberi 19 20 Autumn Winter Collection. A track jacket made of a stretch coated fabric. It has a heavyweight atmosphere like the mainline, but it is light overall including the material, so you can wear it casually in early fall or spring. There is a cord inside so that it can be hooked on the shoulder when you take it off.
