The Brass Knuckle Crusher Safety Goggles, No. BKDST-1020NP, feature contoured channels along the brow line to move water and sweat away from the eyes, while a rubber gasket seals the glasses snugly against the face. The gasket also provides anti-dust protection. The goggles include the company's proprietary BK-Anti-Fog+ technology to offer ideal performance under heat and humidity for a long-lasting, fog-free view. With a wraparound style, the one-piece 10 base curve lens offers high-impact protection and an unobstructed field of vision. Super-flex temples hug any size face and TempleTouch technology comfortably grips the sides of the head with molded-in nibs behind the ears.
