SLACK was already a bold model and its versatility made it suitable for any situation. The SLACK COVER features the same characteristics of lightness and comfort, with the addition of removable protections on the sides and above the bridge that transform these vintage glasses into a real accessory for exploring the peaks. They feature a boldly styled double-bridge frame, and are available with three types of lenses, including SPECTRON HD Polarized: a polarized lens that amplifies details, emphasizes and highlights contrasts and colors, and reduces eye strain for ideal comfort, all day. SLACK COVER, with its unique protection, will make you love the mountain wind.
