This is a comfortable, sharp vintage Adidas jacket. The jacket is reversible and has snap buttons. They grey material is like a sweat pant type fabric (very comfy) and the red material appears to be nylon. There is no tag on this jacket. I am 6'5 and the jacket fits me fine - even in the arms. Measurements are in the photo - 29 inches from shoulder to bottom and 25 inches pit to pit. Which is why i list as XL.
It's in good shape but there are some issues to note. There is some dark staining in 2 spots on the nylon left front side and a small spot on the back of the nylon. The left sleeve has a dime sized hole down by the cuff. There is some separation at the seam in the right pit on the nylon side. All these issues are in the pictures.
I would estimate the age at being from the 70s. I haven't seen another jacket like this. It came from an estate of a college basketball player from the late 60's.
