Oakley taps into its surfing heritage with the Hydra Prizm Black adult sunglasses including a semi-rimless frame inspired by the Razor Blade style. Featuring the Oakley B1B logo on the temples, Hydra sunglasses are accentuated by a modern trigger stem design, reminiscent of Razor Blades' origins in surf culture. A lightweight and durable plant-based BiO-Matter® frame and a three-point fit system, as well as a high bridge, help provide balanced fit and comfort. For enhanced colour and contrast everywhere you go, Prizm™ lens technology provides the details.
