TYR Nest Pro Goggle Thermoplastic rubber Imported Made using the highest quality materials Tested to give you the edge in all your activities Used by both professional and recreational users 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.
