We offer the Aqua Sphere KAYENNE glasses during the lessons. Aqau Sphere leads the way and offers the best Aqua Sphere technology for swimming. The Aqua Sphere Kayenne goggles have a unique oversized lens design, this combined with superior hydrodynamics due to the "low-profile" micro frame makes the Kayenne a perfect choice for competitions, in both a pool and in open water. The glasses have a 100% Softeril face piece with regular-fit fit and stabilizing nose bridge which provides a very comfortable and leak-resistant seal. Hypoallergenic Softeril is an exclusive material that offers long-lasting comfort and durability. The extra large Plexisol lenses give you a field of view of no less than 180 degrees and are enlarged at four points for even more view. Plexisol is 10 times stronger and 100 times lighter than glass and is ultra durable and free of distortion. The lenses have a scratch-resistant coating and are pre-treated with anti-fog to prevent condensation. The headband is made of silicone for extra comfort and durability and the one-touch, Quick-Fit buckles allow you to adjust the headband with one simple move, even while wearing.
