Safety goggle

October 1, 2011
The SG-1 Goggle meets ANSI-Z87.1-2003 optical, high-velocity and high-mass impact standards, providing significant protection against eye dangers in the workplace. The goggle can be converted from a spectacle to a goggle and back again. Standard temples are included and can easily be removed from the frame and replaced by an adjustable elastic strap.
