Under Armour Athletic Running Workout Shirt Gray

Gray Under Armour Running Workout Athletic Shirt. Great condition. 84% Cationic Polyster material content. There is a small white speck near the logo. This is not bleach or a stain, but rather an anomaly in the space dying of the item. See pics. Armpit to armpit measurement is 17”. There is no size tag, but guessing this is a Size Small.
