A3 Performance's Avenger X Goggles are only one of the most popular goggle styles in the water! So how did A3 Performance make the Avenger X the most comfortable goggle in its class? We increased the surface area of the gasket and designed the silicone gasket to hug the curvature of your face around your eye, making A3's Avenger X considerably more comfortable than other, similar styles. You've got to try this for yourself! The Avenger X is ideal for fitness and competitive swimmers.
