The Twist Four VL+ from the Performance series is designed for ambitious all-weather athletes who value three levels of protection with photochromic lenses. The Varioflex lenses automatically adjust to the ambient light, and the Fogstop coating ensures fog-free visibility. Perfect adjustment options are provided by the adjustable nose pads and temples. Protection level: S1-3.

Optimized airflow: The strongly curved lenses envelop the face perfectly. They protect the eyes from drafts and cold while improving visibility. The indirect airflow design prevents the lenses from fogging up.

2-component design: The combination of a hard frame, soft temple ends, and nose pads enhances comfort and fit of the glasses.

Twist Fit Nose: The nose pads can be infinitely adjusted through a ratchet mechanism, allowing them to adapt individually to any nose shape.

Adjustable tilt: A tilt-adjustable temple joint optimizes the fit. Tilting the glasses towards the forehead ensures freedom from pressure, while tilting away from the forehead increases ventilation and prevents fogging of the lenses.

Varioflex: Varioflex is a lens technology that automatically adjusts the lenses according to the weather conditions. The photochromic lenses react either to UV light (for glasses with protection level S 1-3) or to visible light (S 1-4). When exposed to light, chemical elements open up, creating a darkening effect. As the light intensity decreases, the chemical elements close, and the lenses become lighter again. This process happens in seconds, providing you with glasses that adapt to constantly changing light conditions.

Fogstop: Fogstop is a coating on the inside of the lenses that is not smooth but rough. This texture prevents droplets from forming a continuous layer, thus avoiding fogging and obscuring vision.
