Even the world’s best athletes start out small, so Oakley engineered a youth frame that’s big on protection. The look is pure Oakley and the science is High Definition Optics (HDO®), a collection of technologies that maximize clarity. Pure Plutonitelenses filter out 100% of all UVA, UVB and UVC, and combined with this durable O Matter frame, they meet ANSI standards for impact resistance. The “XS†stands for “extra small,†so these sunglasses are for the young and reckless.
