The HSTN feature the same progressive design and heritage features as the original, including striking modernized circular lenses and a modernized trigger stem. The frame features plant-based BiO-Matter® material that helps provide the same all-day comfort Oakley has long been known for, alongside Unobtainium® nose pads for unparalleled comfort and improved grip. Also, for enhanced colour and contrast everywhere you go, Prizm™ lens technology provides the details.
