The Lacoste L907S sunglasses are made of high-quality Nylon to make them durable, long-lasting, light and hypoallergenic. The Injected Plastic lenses are also shatter-proof and can block 100% of UV rays. The non-slip temples of these Lacoste Sunglasses bear the well-known Lacoste logo, the crocodile. The hinges, nose pads, and nose bridges provide a nice and steady fit.
