Adidas like vintage track jacket red/navy

Awesome track jacket red and navy. The tag in it doesn’t have a size but it fits me perfectly and I’m a medium...just the right amount of loose fit that you want on a track jacket if you’re a medium (not too tight or too baggy) the zipper has a B on it and so does the chest area. For being from the 70’s item is in very good condition. Purchased on Haight street years ago. Made of the same material as most vintage adidas jackets that kinda silky smooth 60’s track jacket vintage adidas jacket
