The shape and structure of the silicone is perfectly aligned with the eye sockets, facial contours and eyebrows, creating a perfect hydrodynamic symmetry with the face. When swimming fast, you will especially appreciate the unique stability and comfort of the Tiger LSR, qualities which fulfill the wishes of the most demanding athletes. The hydrodynamic shape of the Tiger LSR creates a very low internal volume and a perfect seal around the eyes. The soft silicone and the nose-bridge construction make the goggles easily adaptable to a wide range of face forms. The exclusive design of the curved, conical lenses, which follows the natural visual cone of the eye, creates an extraordinarily wide field of vision and reduces the annoying optical distortions often experienced underwater.
