Awesome leather jacket. Love it. I was a little nervous about sizing as by my measurements it said i needed a 2XL (I usually wear L or XL) but i went with Master Supplies sizing suggestions and the fit was great.
I think this is the nicest leather jacket I ever had. Heavy leather too. Should be a lifetime jacket.
