With the inclinable temples the glasses can be adapted individually to the face form. In the small version it fits perfectly on narrow faces. 100% UV protection is provided at all times. The Twist Five HR S VL+ is the perfect pair of glasses - for any weather, for any sport.
Varioflex
Varioflex is a lens technology in which the lenses adapt automatically to the weather. The self-tinting (photochromic) lenses react either to UV light (for glasses with protection level S 1-3) or to visible light (S 1-4). When irradiated, chemical elements open and produce a flat, darkening effect. If the light intensity decreases, the chemical elements close and the panes become brighter again. This process takes place in a matter of seconds. So they have glasses, which adapt themselves to the constantly changing light conditions.
Fogstop
Fogstop is a coating on the inside of the lenses that is not smooth but rough. This means that the drops have no possibility to form a closed layer, i.e. to fog up and thus obscure the view.
Adaptable Nosepad
Cold adjustable, rubberized nose pads allow optimal adaptation to any nose width and shape. The rubber coating effectively prevents slipping and guarantees a secure fit.
Adjustable Inclination
Thanks to adjustable temple joints, the glasses can be tilted away from the forehead during the sweaty uphill. Downhill tilting to the forehead reduces draughts. For sports with a fog-free view at all times.
2 Component Design
The combination of hard frame, soft, rubberized temple ends and nose pads increases the wearing comfort and fit of the glasses.
Optimized Airflow
A strongly curved eyeglass lens in combination with an indirect air flow guide ensures draught-free and fog-free vision even during fast outdoor sports.
