The Aqua Sphere XCEED Goggle with Smoke Lenses have been developed in collaboration with Michael Phelps, the greatest Olympian of all time. Engineered with Exo-Core Technology, this goggle has a one-piece streamlined design for optimal hydrodynamic performance and fit. Further adding to this supreme fit are the interchangeable nose bridges. With four different sizes included, you can easily find the one that best suits you. The highly durable polycarbonate lenses have been treated with antifog and anti-scratch technology, so your vision remains unhindered throughout your entire swim. Curved Lens Technology widens your field of vision, allowing you to see the full 180Ëš of what is around you.
