Good Jacket Runs Large
I am 5,8' and normally wear sized M-L jackets depending on the maker. I love 686 because their craftsmanship is top-notch and steezy so I purchased this bad boy last winter. I ended up returning it because it was too big even with base layers. The arms actually extended several inches past my fingertips and I looked shapeless even with the cute belt. So just keep that in mind when purchasing a size; I would shoot more on the modest end.
