Sizes As no two faces are the same Zoggs have created two unique adult goggle sizes for their Predator goggles: * Regular for a standard fit around the eye socket * Small for smaller faces or an inner eye socket fit Testing Zoggs Predator goggles have been tested in all environments from indoor pools, Icy lakes, sea and rivers and tested on 100's of faces, to help fit yours.
