I've read through most of the comments on sizing I could find and got some feedback from both TS and GB on the moto jacket fit (GB said go M, TS said try S). Wondering if anyone on here with similar measurements can share their experience with the moto jacket. I am 5'9" and 155-160 lbs. Athletic build. Chest measures approx 37, 38-38.5 expanded. I see the note on the jacket fitting snug. I plan to wear it over tshirts and henley's, perhaps the occasional long sleeve button up or flannel. Don't need it to fit over a thick sweater.
I am not a big guy and I feel that makes my "margin for error" in sizing a bit less. I don't want to be gasping fir air in a small or, swimming in a medium. I guess I am your typical smedium guy.
Anyhow, any inout from someone that's ordered a S or a M would be greatly appreciated. And I do realize they take exchanges but am hoping to get this right first time around.
I'd go for an S. We have similar measurements (I'm a touch shorter than you), and the S fits me well.
