These Harley-Davidson HD400 Series glasses are no exception to the brand name trust. These safety glasses are built to protect and last while still looking very stylish. The 9-base wrap-around lens provides the wearer with 180 degrees of panoramic vision and excellent side and brow coverage. The HD400 comes with a black break-away adjustable Harley-Davidson retainer cord for any extreme circumstances you find yourself in. Of course these glasses meet the 2003 ANSI Z87+ and CSA Z94.3 standards.
