The Line Miner L goggle was created with the purpose of providing the ultimate in peripheral vision, with a cylindrical-style design. With a large-sized fit, Line Miner L is optimized for a wide variety of faces and is engineered to fit perfectly with most helmets. Features Oakley’s Prizm lens technology has been specifically engineered to enhance visibility and contrast over a wider range of light conditions. The Iridium coating on the outer lens reduces glare from the sun/snow. With High Definition Optics (HDO), the lens is cut thicker over the optical centre and thinner towards the edge, helping eliminate any distortion. High-grade Plutonite lens material is engineered to give clear, sharp, and accurate vision while offering protection against impacts. The flexible O Matter frame conforms to the shape of your face. Low-profile frame design brings the lens closer to the face to increase peripheral vision. 50mm silicone backed strap keeps the goggle securely in place, even on a shiny helmet surface. The frame has discreet notches allowing compatibility with most prescription eyewear. Triple-layer polar fleece foam creates a solid yet comfortable/dry fit. 100% UV protection.
