The innovative Arena Unisex Competition Goggles Cobra Ultra Swipe Mirror are ideal for competitive swimmers. The revolutionary Swipe Anti-Fog Technology lasts ten times longer and can be reactivated by gently wiping the inside of the lenses with your fingertip. To do this, carefully wipe the inside of the lenses five times with your fingertip while the goggles are in the water. Simply repeat this procedure whenever the lenses start to fog up again for clear vision over an extended period. The small frame profile and narrow seal ensure a stable fit in the eye socket and minimize water resistance. The curved and angled lenses provide optimized frontal visibility as well as a good side view of competitors. The package includes five interchangeable nose bridges that allow for a customized fit of the goggles to different face shapes and nose sizes. The double head strap can be perfectly adjusted via a buckle at the back of the head, ensuring a stable fit even during starts and turns. The unique temple system gives the goggles additional stability. The goggles are equipped with dark mirrored lenses, UV protection 400, and are PVC-free. The sturdy Arena Swim Goggles Case, for the protection and safe transport of the goggles, is sold separately.
