Ellume Polarized
Reflected light and UV exposure can cause glare, eye fatigue and sensitivity, all of which disrupt your experience outdoors. Ellume Polarized eliminates 99.9% of glare and blocks 100% of harmful UVA/B rays, protecting against the risk of long-term eye damage.

Z-Lite Thin Injection
Z-lite combines our Z-Resin material, which includes a minimum of 45% bio-resin, with a thin injection process, creating an ultra-lightweight, durable frame, weighing in at less than an ounce including the lenses, for performance and style.

Durability
From the frame to the lens, all Zeal Optics sunglasses are designed to stand up to everyday life as well as the world’s harshest conditions and we've got the warranty to back this up.

ProFlex Rubber
This unique, porous rubber material is strategically injected into the temples and nose pads of the frame to provide a soft and comfortable hold that gets tackier as things warm up, keeping your glasses in place regardless of conditions or activities.

"The Harbinger sunglasses from Zeal Optics are hands down the best eyewear I’ve ever used for mountain biking. The lens clarity is insane — I can pick up every root, rock, and line change even when darting between shadows and sun. They stay locked in place no matter how rough the trail gets, and the Anti-Fog baked into the lens keeps them from steaming up, even on steep climbs. Plus, they’re tough — I’ve taken a few tumbles, and they’re still scratch-free and solid. These shades don’t just keep up — they lead the way." - Rafa Infante, Zeal Ambassador
