Leffingwell features a full rim, square lens shape infused with design inspiration taken from the craftsmanship and finishes of surfboards and the lifestyle around surfing. The plant-based BiO Matter frame has antique-finished decorative elements and textured temples. The subtle Oakley logo on the temples is designed for those who gravitate toward subtle, elevated design aesthetics. Leffingwell comes with Prizm (TM) Lens Technology designed to enhance color and contrast to see more detail across the water and beyond.
