These new Hercules Safety Glasses are practically indestructible! We stepped on them, stretched them out straight as hard as we could, even twisting them; then we ran over them with a forklift and they didnt break! The lenses came out of the frame, but we just poppedthem back in. Meets ANSI Z87.1-2010 Standards. Shatter proof polycarbonate lenses have a scratch resistant coating. Nylon frames with rubber ear pads. Excellent wind shielding along and UV400 filter for maximum UV protection. Ship wt .5 lb.
