The Oakley O Frame Heritage MX goggles boast an F2 anti-fog, scratch-resistant and impact-resistant Lexan lens. All Oakley lenses offer HDO Technology, which gives less distorted vision and a truer visual image so your brain won’t have to work overtime and block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm. Triple-layer face foam fleece wicks away sweat, and the O Frame is composed of ultra-strong, yet lightweight, O Matter combined with flexible urethane.
