This is what you get after 16 years of painstaking R&D: killer-looking eyewear that endures a world of hurt without letting anything get in the way of clear vision, fit, or comfort. Constructed of virtually indestructible Grilamid®, the Quanta 2.0 features the Scoop® ventilation system to increase airflow and decrease fogging, interchangeable 8-base polycarbonate ARC® lenses, and slip-resistant rubber nose pads and temple tips.
