This vintage Adidas Originals track jacket in white is a medium size and features the iconic Great Britain design. Made from 100% polyester, it is a stylish piece of activewear for men. The track jacket has a classic track jacket style with a zip-up front and is part of the Adidas Originals product line. Perfect for casual or sporty occasions, this jacket combines comfort and style effortlessly. As seen in the pictures the item does have some yellowing due to its age. The jacket is nearly 20 years old and I purchased it from new from a boutique in Norwich.
