Julbo says about the Aerolite
Lightweight sunglasses specifically designed for women and runners with smaller faces, AEROLITE is directly derived from the AERO model, a benchmark 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 REACTIV Photochromic lenses, AEROLITE is designed to go further in all conditions.
