Description: SONIC single-piece swimming goggles are made of extremely soft, flexible and non-toxic silicone, pressed using the LSR (Liquid Silicone Rubber) technique. It ensures the highest comfort of use, guarantees the durability and durability of the glasses, minimizing the effect of material aging. LSR also means high resistance to damage and a guarantee of maintaining flexibility lost as a result of high and low temperatures and UV rays. The lenses of SONIC glasses are made of damage- and scratch-resistant polycarbonate (Hard High Grade Polycarbonate). They have tinted glasses with an anti-fog surface and a UV filter. The modern shape ensures low air volume inside the glasses. Combined with the properties of LSR silicone, it makes SONIC glasses easy to fit and adapt to many face shapes. The location of the glasses lenses close to the eyes and their shape accelerate the flow of water around the glasses, maximize the field of view and minimize the effect of image distortion both above and under water. Easy Clip fasteners allow you to quickly, easily and conveniently adjust the belt tension. The flexible attachment of the strap clasp ensures its natural position and minimizes discomfort and tension on the glasses. Glasses intended for teenagers and adults.
