Nike Track Jacket Colors: Navy, Orange Made of jersey fabric, easy to wear, and I think it's also suitable for exercising. Although it's not very noticeable, there are some pills here and there. The zipper pull is missing. I received this from someone, but I didn't wear it much and it's now too small. Please understand that this is a used item and has been inspected by a non-professional. There are no pets or smokers. Thank you very much!!
