NITRO RACING Men's black padded dura guard motorcycle jacket size small

Nitro Racing black padded motorcycle jacket size small Zip out lining and removable pads in back, arms, shoulders and chest. Mesh material on exterior. There is one zip flap on the inside portion that’s hanging down and I have no idea what it’s for. I guess you could cut it off if it’s not functional - it is shown in the last picture. This jacket is an excellent condition. Approximate Measurements: Pit to pit laid flat: 23” Length Shoulder to Hem: 25”
