Thanks for the info DLester!
I'm hoping the padding isn't substantial and that I sized right in the M. I think the L would have been too long in the sleeves and I don't want to be modifying this jacket. Totokaelo is supposedly wearing the M and it looks to be a regular fit. He's quite a bit taller than me and not exactly skinny.
I tried on a suede bomber a few months back and really fell for the look.
