The Pyramex Capstone Shield, when used in conjunction with the Pyramex Capstone 500 goggle, provides full face protection. Not only do you get all of the eye protection with the goggle, but the Capstone Shield ratchets to 3 different positions. Constructed of Polycarbonate, this shield conforms to the face, offering increased impact and dust protection. Also included in the design is the indirect-vent frame, which provides protection against splash and dust.
