Goggles feature sleek, wraparound styling to provide a 180-degree field of vision. Anti-fog coating maintains proper vision and offers excellent acuity. Adjustable elastic headband ensures a secure, comfortable fit. Pivoting headband clips let you easily adjust the strap around hard hats or hearing protection. Goggles can be worn over most prescription eyewear and half-mask respirators. Clear polycarbonate lens can be used with peel-off goggle covers (sold separately) to extend the life of the lens.
