Harley-Davidson Men's Iron Bond Shirt. 99004-23VM. This men’s short sleeve shirt features a hit of contrast from its piecing and piping, and a hit of practicality from its hidden snap-down collar that stays put while you ride. Finished with our beloved Bar & Shield in a pop of orange on the chest for a look that’s authentically Harley-Davidson. Materials: 100% cotton twill with specialty wash for faded appearance.
