C3 OPTICS: Our ultralight nylon lenses offer best-in-class, razor-sharp optics with anti-scratch, anti-reflective, anti-fog, hydrophobic and oleophobic coatings. ULTRA-LIGHTWEIGHT FRAMES: Our TR 90 nylon frames are significantly lighter than industry-standard materials like acetate and polycarbonate without sacrificing strength or durability. GEKO Patented Fit and Retention System won't slip off your face and forget about those painful pressure points on your nose. Inspired by the soft but amazingly sticky feet of the Gecko, our patented GEKO fit and retention system features a proprietary elastomer for nose and temple pads that's hydrophilic, chemical resistant and supports multi-directional traction with comfort.
