Ok so I went today and tried them on. I ended up getting the black one as I thought it was the nicest. The 'leather' is matte and not shiny at all in all of the 3 colours.
Ohhh...I think I've been looking for the wrong jacket. I went and tried on the ON denim jacket and it was tight in the arms. I might have to try the moto jacket now. Can't go wrong with black.
