Why we made it.

The smaller sibling of our Halsey glasses, this timeless silhouette is great for smaller faces. It's packed with tech and features to make it fit, feel, and perform like a cutting-edge frame, but we crafted it to look like something a bit more casual. Take them anywhere you want to go, they won't let you down.

“Honestly, I never thought I would spend more than the $15 gas station sunglasses. But I figured I would try these and see if they lived up to the hype. We do a lot of outdoor activities. These are the real deal. No slippage, perfect for biking, hiking, all outdoor stuff. I liked them so much I bought a second pair. Very happy with them and recommend to everyone I know.”

“My previous iterations of eyeglasses tended to either fall off or swing from my ears when facing down. The grips on my ROKA Zilker pair keep everything in place, even with decent movement, and they are lightweight for their chunky frame.”
