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 MELON HEADS: A larger frame built specifically to accommodate those with magnum-sized noggins., 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.
