Our Technoflex® 4.0 technology involves a revolutionary dual injection manufacturing process. With the same great fit as the original Technoflex® goggle, the Technoflex® 4.0 features gaskets that are injected with a softer durometer material to improve comfort and fit. The goggle also incorporates differing hardness densities of Thermo Plastic Rubber (TPR) as well as a stiffer durometer material to provide frame rigidity, which prevents nosebridge stretching.
