The Oakley XS O-Frame MX Goggles are optimised for smaller faces and offer anti-fog, scratch-resistant and impact-resistant Lexan lenses. Three-layer fleece foam wicks away sweat and is ultra-comfortable. The frame is made of Oakley's O Matter, an ultra-strong and ultra-light material combined with flexible urethane and a silicone headband. It is Tear-Off compatible. All Oakley lenses feature HDO technology, which provides less distorted vision, a more realistic image for less brain fatigue and blocks 100% of UVA, UVB & UVC rays, as well as blue light up to 400nm.
