NO SLIP: We use a special grip coating and silicone nose inserts to construct our frame to help eliminate slippage when sweating. NO BOUNCE: Our frame is snug and lightweight, with a comfortable fit to prevent bouncing while crushing any workout. ALL POLARIZED: We use glare-reducing, polarized lenses with UV400 protection that blocks 100% of those harmful UVA and UVB rays. ALL ANGLES: Angular, fashion-forward frames that are always trending...even if you aren't. ABOUT GOODR: In 2015, goodr was created to solve a problem: running sunglasses were expensive, ugly, and over-engineered. To solve this, we set out to design a pair of running sunglasses that were affordable, stylish, and all-performance. And so, goodr was born. BOOM. Problem solved. You're welcome. Trendsetter. Innovator. Vanguard. Visionary. You've heard it all. *Sigh* We totally get it. We designed these swank tortoiseshell Vanguard Visionary Pop Gs with fashion icons like you in mind. Now go forth and slay.
