Nike. Not sure what to call this. Size is medium . Color is like mint blueish. Built in attached short with thumb hole with also a flap to cover the whole hand. Would be a great fall or colder weather running jacket or something to use outdoor. The liner shirt is a little thicker. Had a hood. Has a zipper pouch in front for packing the outer layer when not needed. *see pic. Turns into a shirt or light jacket when needed. Very unique. Excellent condition. Smoke/pet free home.
