Zoggs Predator Flex Small tinted swimming goggles for swimmers & triathletes with narrower faces After long testing phases with many hundreds of swimmers of all abilities and ages, we can now offer swimming goggles that almost perfectly match the individual face shape and the individual desire for comfort. With Ultra-Fit gaskets designed for ultimate fit and comfort to ensure the lightest and most comfortable fit. The 3D Flexpoint has four flex points that allow the frame to completely mould to the contours of the face. These goggles are ideal for indoor swimming but can also be used in open water. Zoggs has even added UV protection, anti-fog and CLT-Curved Lens Technology for extra protection and clear vision.
