I tested the Aqua Sphere Kaiman Exo Mirrored Lens Swimming Goggles out at my local public sports pool where my routine is to swim 60 lengths (1 mile) once a week. The first difference I noticed between my normal goggles and these was that the nose bridge wasn’t adjustable. I thought this was going to be an issue but they fitted my face with comfort, normally I have had to use the smaller nose bridges on goggles but this one size fits all system was compatible for both me and my swimming partner (who is more well-endowed in the nasal region).
