I'm 6' 2", 190 lbs and I bought a large. I have long arms and this fits me well. It would probably still fit well if I weighed another 20 lbs. Finally, women are willing to talk to me. In fact, one approached me the other day and said something to the effect of "Is that your car there? That's a handicapped zone and I don't see a sticker on it." It wasn't even my car. I would have kept talking to her, but she seemed so powerful and gorgeous. Baby steps. I feel like a new man.
I see a lot of reviews saying this is not what they wanted, but that is entirely due to their thinking that this is a thicker version of the same design. This is shipped from Adidas, so it would be really unlikely for it to be a fake. Adidas makes athletic apparel and you can expect some items to be light for certain weather and some to be heavy. This jacket is light and the price reflects that. I bought it because I expected that, so, 5 stars. So easy, when you don't build things up to be something bigger than they actually are. My therapist says that works with women, as well. Time will tell.
