Aviator Nation Grey Sweats With AV Logo Size Womens Medium This is a well loved pair of Aviator Nation sweats. The price reflects the wear, and I want to note that the elastic waist band has stretched out a bit and doesn’t have the hold it used to. This would be an easy fix with a drawstring, or if you prefer your waist band loose, this is the pair for you. I’d say with the stretch they fit more like a large and not a medium.
