UA Lightweight Pullover

Under Armour lightweight half-zip pullover. EUC. No tag that i could find (there doesn't appear to have been one removed either...?) but my guess is it's a Medium? Measures (laying flat) about 18 inches pit to pit, 24 inches long, 24 inches arm length. REFLECTIVE UA logo on the color and reflective wording on the back of one shoulder. Has one discreet side pocket that kind of goes toward the back of the top, if that makes sense? Thumb holes/loops COLOR is a deep blue(darker than in photos).
