Borrowing from our award-winning performance sunglasses, the frames of the Lockhart feature ultra lightweight TR-90 nylon, which are lighter than acetate or polycarbonate, nearly unbreakable in daily use, and impervious to chemicals. They have integrated spring hinges, which last longer than traditional barrel hinges and flex with different head shapes. The Lockhart also features our proprietary GEKO™ technology, both in the temple grips and in our patented, interchangeable nose pads. GEKO™ is a hydrophilic compound designed to get tackier when wet or sweaty, which helps our glasses stay in place when you're active – working out, hiking, bending down to pick up the groceries, or playing with your pets or kids.
At the end of the day, all of this tech is meticulously engineered to deliver the performance you'd expect from sport glasses without having to look like you are about to step onto a racquetball court.
The Lockhart is assembled by hand at our own optical lab inside our Austin, Texas, headquarters and is available for direct purchase in a variety of premium lens configurations. It can also be made in non-prescription sunglasses, a regular distance prescription, progressives, and prescription sunglasses.
Weighing in at just 22 grams, Lockhart is 50% lighter than the competition thanks to its TR-90 nylon construction, which weighs significantly less than industry-standard materials like acetate and polycarbonate without sacrificing strength or durability.
Our finely tuned, integrated spring hinges are engineered for comfort, fit, retention and durability. They'll feel the same use after use—without loosening even after years of repeated wear. The lateral flex also accommodates a wide range of face widths and head sizes to eliminate uncomfortable pressure points.
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. No matter how sweaty you get and which way you move, bounce or shake, you’ll never have to worry about slippery frames sliding down your nose or falling off your face.
