Mountain Biking Sunglasses

Polarized Mountain Biking Sunglasses

Mountain Biking sunglasses from Zeal Optics are designed to help you see every inch of the single track. Equipped with Proflex rubber on the nose bridge and temples, Zeal sunglasses stay in place whether you're sweating it out on the uphill or cruising on the downhill. Our plant-based Ellume Polarized lenses enhance color, clarity and contrast so you can focus on every obstacle and feature that comes your way.


Z-Lite Thin Injection

Z-Lite combines our Z-Resin frame material with a thin-injection process to allow for an ultra-lightweight, super durable sunglass frame for complete versatility no matter the activity.



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.

On & off the bike I wear Boone

"The Boone sunglasses by Zeal Optics are my favorite as they are so light I don't even notice them while out on a big adventure. They don't slide around on techy terrain or fog up on the climbs. They are the best sunglasses in varying sunny conditions with Ellume polarized lenses.

I need a pair of sunglasses I can throw in my pack and not worry about them breaking and I can tell you these sunglasses have been around the globe adventuring and are still in one piece thanks to the flex design which is light and strong.

Also, 100% plant-based so I can ride knowing the sunglasses I'm wearing were made with care for the environment in mind."
