The innovative Arena Cobra Swipe Mirrored racing goggles from Arena are the ideal companion for competitive swimmers, triathletes, and open water swimmers.  The new Swipe version of the Arena Cobra range have special antifog technology that keeps them from clouding for up to 10 times longer. If you find that your goggles are fogging up gently swipe the inner lenses five times with your fingertip while the goggles are in the water, making sure there is no dirt on the lenses while doing so. Do this every time lenses become foggy to enjoy clear vision for longer.  The mirrored lenses reduce glare and brightness, ideal swimming under bright lights or for outside for open water swimming. The low profile frame and the sleek seal provide stable fit in the eye socket and minimize drag. The Arena Cobra Swipe swimming goggles come with 4 interchangeable nose pieces so that you are able to get the best fit. The split headband can be quickly adjusted with the easy-to-use buckle and ensures a solid fit on start and turn. Like all arena goggles, the Cobra Swipe goggles feature UV protection 400 and is PVC free.  Features: Low profile racing goggles Antifog reactivated with a simple gesture Split headband for solid fit on start and turn UV protection, antifog treatment, PVC free Also for triathlon and open water swimmers
