Spy Libra Sunglasses These SPY Optic Libra sunglasses were designed and built from scratch, making a women's-specific performance frame that's both beautiful and talented. They are built from high-quality Grilamid and feature 8-base Victory lenses, a patented Scoop ventilation system, 100 percent UV protection, and Hytrel temple tips for superior comfort in a smaller frame. SPY didn't just pink it and shrink it when it came to these Libra sunglasses. They put time and dedication into a true woman's performance pair of shades.
