Fogging is minimized by the Whirlwind ventilation system, which circulates air through the optical chamber. Ten conical air chambers line the frame's brow area. Secondary air enters the goggle through ten additional ventilation ports on the frame's underside, creating a whirlwind of air that circulates through the inner frame.
They are available in a variety of one-piece lens options, and dark green 3.0 or 5.0 IR filter shades for light welding applications. A foam insert for added comfort and protection is also available on the frame with clear anti-fog and gray anti-fog options.
