This jacket wins! What has really won me over is the fit. I'm 5' 7" and 125lbs, with long arms. I have a hard time finding jackets that fit just right, usually for the body of the jacket to fit, the sleeves or torso length come up short and sizing up means its swimming around my midsection. Not on this one, the small fits me perfectly. I even have room to hide my hands in the sleeves! This is a pretty big deal for me.
As many other reviewers have attested this jacket is pretty warm for the weight. The fabric is loud, but I don't care considering how light it is and how well it fits. Also, I think it's a pretty ideal weight for layering under a shell for super cold temps.
Furthermore, I think the styling and colors are awesome, and this thing puts my old down sweater to shame.
