The half-frame version is a classic product from the TWIST FIVE product family. Thanks to the high-quality QuattroVarioflex lens technology, the glasses offer a very wide range of applications. The reflective lens is polarized, improves contrast and adapts optimally to the lighting conditions (it is photochromic). The Fogstop anti-fog protection prevents the glass from fogging up due to its water-repellent protection, as it more easily reflects water and dirt in droplets - this always ensures a perfect view. The bendable arms allow you to individually adjust the glasses to the shape of your face. The glasses offer 100% UV protection.
