The Oakley HSTN SQ delivers a sharper, more angular take on the original HSTN design. Its squared-off silhouette and modular colour play create a bold, modern look, while premium metal details give the frame an elevated finish that works for both casual wear and active lifestyles.
Built with Oakley’s O Matter frame material, the HSTN SQ is lightweight, durable and designed to maintain its shape over time. The injection-moulded construction provides improved flexibility and strength compared to traditional acetate frames, making it ideal for everyday use.
Unobtainium nosepads increase grip with perspiration to help keep the sunglasses securely in place throughout the day. Oakley’s Prizm lens technology enhances colour and contrast for clearer vision in bright conditions, while the lenses are tested for impact protection in demanding environments.
Designed in a regular universal fit, the HSTN SQ comes in size L with a 133mm frame width, 54mm lens width, 21mm bridge width and 142mm arm length, making it a versatile option for a wide range of face shapes.
