2XU reversible, technical sports jacket. Perfect for colder weather and any sports activity like running, hiking, climbing, cycling. One side is black, the other side navy blue. It is absolutely stunning, the photos are really not good and not doing it any justice. If you are familiar with 2XU, then you know that their items are of the highest quality. Unfortunately it doesn't fit me and probably never will. It is a size M and athletic fit. Happy to provide measurements if required
