Over the years, the brand has expanded into additional categories including apparel, footwear, and accessories, yet the California-based company remains best known for its high-performance eyewear. Oakley is consistently at the forefront of eyewear innovation — currently holding more than 600 patents — with high-tech designs that include interchangeable lenses, high optical clarity, and damage resistance. While many of its glasses cater to a specific sport or activity, Oakley frames in general have become increasingly popular in streetwear and high fashion circles, as the brand now appeals to those looking for performance and lifestyle options alike. Per the name’s implication, the Flak 2.0 XL is an XL edition that boasts a standard size frame with amplified lens coverage, as the peripheral view is optimized with High Definition Optics. The glasses are suitable for bright light conditions thanks to Oakley’s Prizm lens technology, which is designed to enhance color and contrast so you can see more detail.
