Gist glasses Pack photochromic

The wide and comfortable wraparound lens combined with an ultra-light frame make Pack glasses with a full-coverage design and a wide field of vision for pedaling in complete safety.

PHOTOCHROMIC version. A version that allows the lenses, exposed to UV radiation or sunlight, to start a reversible chemical reaction that leads to a gradual darkening, to return to the initial state of transparency when the irradiation of light or UV rays disappears.
