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. It's also designed not to snag hair. No matter how sweaty you get, and which way you move, bounce, or shake — you’ll never have to worry about slippery frames falling off your face.
