In athletic stores, you'd pay much more for these New Balance sunglasses! They're designed to meet the needs of your lifestyle and feature interchangeable lenses that let you tailor the performance to the light conditions. Use the polarized anti-glare lenses for everyday conditions. For brighter days, pop in the reflective mirrored lenses. Both lenses block virtually 100% of UVB and 98.5% of UVA rays for exceptional protection. Also features wrap around styling, gunmetal color frames and rubber-temples.
