The innovative arena unisex triathlon goggles Cobra Tri Swipe Mirror are perfect for triathletes and open water swimmers. The revolutionary arena Swipe Anti Fog technology lasts ten times longer and can be reactivated by swiping the lenses with your finger. 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 small frame and the comfortable seal provide stable fit in the eye socket and minimize the drag. Delivered with three interchangeable nose bridges for perfect customization to different face and nose shapes. The dual strap is easily adjustable at the back of the head and guarantees stable fit, even during start and turn. The goggles are equipped with dark mirrored lenses, UV protection 400 and are PVC free. A hard arena goggles case for protection and safe transportation of the goggles is available separately.
