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 surrounding brightness, 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: Nose pads that can be rotated infinitely via a ratchet mechanism adapt individually to every nose shape.

Adjustable tilt: A tiltable temple joint optimizes the fit. Tilting the glasses towards the forehead allows for freedom from pressure. Tilting away from the forehead provides more ventilation and prevents fogging of the lenses.

Varioflex: Varioflex is a lens technology where the glasses automatically adjust according to weather conditions. The photochromic lenses react to either UV light (for glasses with protection level S 1-3) or visible light (S 1-4). When exposed to light, chemical elements open up and create a darkening effect. As light intensity decreases, the chemical elements close, and the lenses become lighter again. This process occurs 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 visibility.
