Sweet Protection developed their own RIG® lens technology to create superior contrast, minimize color distortion and reduce eye fatigue. And then carefully engineered it into the frameless design of the Connor RIG® Reflect Goggle with Extra Lens, to give the largest field of vision in a medium goggle. So now there’s literally nothing to distract you from being out there. This model also includes an additional bonus lens for low-light conditions, so that you have the flexibility to switch between lens options.
