I have decided to buy analog pants and jacket and definitely need to XS pants, but on the jacket (Analog Solitude), I can't decide between S and XS. I have a 36 inch chest, am 5'8.5" and 125 lbs. I don't want to restrict movement but don't want to be swimming in the jacket. I've heard Analog runs large so I'm leaning towards XS. Can anyone help me out?
