Lightweight sunglasses specifically designed for women and runners with smaller faces, Aerolite is directly derived from the Aero model, the reference for trail runners. It offers the same level of grip and ventilation, with a rimless lens for even more lightness and a tremendous feeling of freedom. With its photochromic Reactiv lenses, Aerolite is designed to go further in all conditions. Photochromic lenses (cat. 1 to 3 - visible light transmission rate: 17% - 75%), they get darker or lighter to match changing light conditions and therefore adapt to any time of day and to the terrain. Internal anti-fog coating and external oil-repellent coating (prevents marking, makes cleaning easier and facilitates water runoff). Ideal for trail running and mountain biking.
