The Kaiman is Aqua Spheres original goggle, and it broke ground for its curved lens shape. The classic design still works great, fits most faces, and is a go-to for many, many swimmers.

The lenses, like all Aqua Sphere goggles, are curved. They work with Plexisol to create lenses that are not only distortion free, but offer a 180-degree field of vision, just like you were looking out of your own eyes.

The frames and the gaskets are made of Softeril, a soft, flexible, hypoallergenic material that conforms and seals like nobodys business.

As with all Aqua Spheres, the lenses are treated with anti-fog and UV coatings for maximum visibility.

The split silicone strap is easy to adjust and holds fast. The nose bridge is flexible and comfortable, and holds everything in place.

There are two sizes, Standard and Small.

There are a wide variety of lens choices. Clear is great for indoor swimmers and all light conditions. Smoke and mirror are great for bright days. Blue lenses have a cooling effect, while the Amber lenses increase contrast and warmth, great for low-light conditions.
