Built for speed and style, the SPY Optic Flyer sunglasses are for people who don't just cruise – they soar. These wraparound shades have a cool, semi-rimless design inspired by bike and running frames, made from super tough Grilamid® plastic that can take a beating. The lenses are the star here: they're Spy's famous 'Happy Lens' technology that boosts color and contrast, makes everything clearer, and is even said to improve your mood and alertness. They're ANSI-certified for safety and offer 100% UVA/UVB protection. They also have a clever Scoop® ventilation system to reduce lens fogging, and rubber pads on the bridge and temples for a secure, non-slip fit even when you're sweaty. The lenses are interchangeable too, so you can adapt to different light conditions. They come with a case for protection. If you need durable, high-performance sunglasses for running, cycling, driving, or any active outdoor life, the Flyers are a top-tier pick that looks as fast as it performs.
