I am 6'1'' and fit in to a small. Would I wear a small, absolutely not. It was much too trim fitting for any type of athletic endeavor. I will be buying a medium. Like I mentioned I am 6'1'' and weigh in at 170lbs. So I am pretty lean. These suits seem to run tall and long in the sleeves. I would compare the fit to that of the slimmer fitting items from Arcteryx. I am a large in all other Stoic gear usually but this one I needed to size down.
