I just got mine in the mail after returning two other jackets. This one fits perfect its snug around the pocket areas and not too baggy long/fat. Looks pretty sick. I'm 5'10ish and 155lb and got a medium. It will most definitely need another layer underneath it for really cold days. But should be fine in the 20+ days. Overall its badass.
1 con though is that the media pocket is in the right external hand pocket but it works fine.
