"I loved the vest, but it runs really large"
I spend a lot of time in vests because it seems to be the perfect compromise during the winter months. If you are going to be outside working out, you need some protection from the elements, but you don't want to be over dressed since sweat + cold = super cold body. I loved the fabric on this vest, but it was too large to be terribly warm. I am 5'9" and 130 lbs. I wear a medium or small as a general rule. I got the medium so I could wear several layers underneath, but even with layers it was too big. I think I would have needed an extra small.
