The Oakley Leffingwell are full rim sunglasses with square lenses and a design inspired by the shape and surfaces of surfboards and the surfer lifestyle. The plant-based Bio-Matter frame has textured temples and the subtle Oakley logo doesn’t look ostentatious or cluttered. The Leffingwell features Prizm™ Lens Technology, which enhances colour and contrast to reveal more detail on the water and beyond. BiOmatter Frame Technology Oakley is introducing BiOmatter as the next step towards sustainability. The technology is a bio-based O-MATTER (frame material) that maintains the same strong and durable characteristics of O-MATTER but is moulded with a plant-based resin made from castor beans.
