The glasses from this model from Bolle are a combination of the technologically advanced nature of metal with a subtle design. Thanks to the 160 ° Flex technology, the distance between the arms can be easily adjusted to your face as the frame is extremely flexible. It can also adjust the nose pads so that the glasses stay in place no matter what activity you are doing. The innovative B-Flex system allows the glasses to fit any face shape, thanks to the exceptional flexibility of the frame. The frame is covered in places with anti-slip material, and the glass has antistatic properties. The glasses meet the European standard EN 172, i.e. they are resistant to UV radiation, so they are perfect for wearing in conditions of excessive lighting. Their mechanical strength is determined by class F. Their design, therefore, protects them against mechanical damage resulting from a direct collision with an object weighing less than 86 g and speed not exceeding 45 m / s. Additional comfort of use is ensured by a coating applied to the glass, which protects them against evaporation and scratching.
