The BXTR are a tribute to Baxter Street, a popular skate spot in Los Angeles where style and authenticity are always on point, just like this frame. The sunglasses were developed by the design team at Oakley® who worked closely with brand friends to explore a new approach to style eyewear. In a nod to the past, the BXTR features a mask design and an updated trigger-shaped arm, inspired by Oakley's original Razor Blade sunglasses, combined with a modern style to enhance their uniqueness.
