If the Shred Optics Stepefy Goggles were any wider, they'd be the industry's first and only panorama goggle. This easy to change spherical lens is Shred Optics' largest. It boasts No Distortion technology, so your vision doesn't get warped. The technology has a small valve to equalize the pressure that causes lens shift at altitude changes, and a high tech Poron filter keeps moisture out. To further keep you seeing clearly, the Monocle's lens block 100% of UVA, UVB and UVC rays and are anti fog treated. The polyurethane frame is built to last, while the universal helmet compatible design, grip on straps and tapered foam are added to make it as functional as possible. It's almost stupid how much and how easy it is to see with these goggles on.
