Our Nest Pro was inspired by the unique bird nest architectural design of Beijing"s main stadium for 2008 Olympics. The structural elements of the Nest Pro"s frame create a unique grid-like effect. * Soft TPR gaskets create a water-tight fit. The gaskets fit around the eye reducing "raccoon eye". * Wide peripheral cellulose propionate lenses feature imbedded anti-fog properties and are UV protected. * Preferred for athletes wanting maximum vision, over the eye extra comfortable fit.
