The Oakley HSTN SQ refines the original HSTN silhouette with a sharper, squared-off shape that brings a more structured edge to the frame. Built with Oakley’s durable O-Matter material, the design stays lightweight while offering the flexibility and resilience needed for everyday wear. Subtle metal details elevate the look, while Unobtainium nosepads increase grip with perspiration to help keep the frame securely in place. Finished with Prizm Grey lenses engineered for bright light conditions, it’s a clean mix of modern design and Oakley performance.
