Technoflex_ 4.0 technology utilizes a revolutionary dual injection manufacturing process, to produce a performance swimming goggle that's strong enough for training and fast enough for racing. Showcasing the same great fit as our original Technoflex_ Goggles, the LGX4 Technoflex_ Goggles feature soft injected comfort gaskets and incorporate differing densities of Thermo Plastic Rubber (TPR), to improve on face comfort and fit. Strengthened frame construction provides rigidity to prevent nose bridge stretching and ensure leak free performance, while anti-fog UV construction enhances protection. Designed to fit a variety of facial types and sizes, the Technoflex 4.0 Goggles are a perfect choice for swimmers of all ages and skill levels.
