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.
