I was impressed with this jacket. Its has stretch all the way around. The style of this jacket is eye catching and is like no other I’ve seen around. It’s not too thin and not too thick either so it’s nice to take to the gym and then after the gym workout. The only thing was the arms were a little long, but it still worked for me. I ordered a large and it fit great. (The arm cuff as stated was a bit long, but I just folded the cuff back a bit and it worked)
