Field-
Tested

Here's Where our Testing Happened.

Tested on the Water. Trusted in the Wild.

Marble’s eyewear isn’t just designed in the field — it’s tested there. Our community of die-hard anglers pushed our specs in high-glare surf, foggy forests, fast-flowing glacial rivers, and tannin-stained backwaters.

SEE BEYOND THE CATCH

Marble Eyewear bridges premium optical performance and sustainable design for anglers. With ZEISS polarized lenses and ultra-light bio-based frames, CHASM is purpose-built to cut glare, sharpen contrast, help you spot fish and read currents in changing light (without added weight). Field tested on 20+ rivers by fly anglers and guides across North America, these sunglasses deliver the clarity, comfort, and secure fit serious fly fishing demands. Each pair supports Marble's mission to reduce fly fishing waste and protect the waters our sport relies on. CHASM is not yet made from recycled fly line; it exists to accelerate our line recycling network that should power future circular eyewear and gear for our sport. This is more than polarized fishing sunglasses. It is a commitment to clean water, a step toward a circular future, and a piece of gear you will trust on and off the river.

Don't Lose Your Marbles.

Every pair of Chasm sunglasses comes packaged with intention. The custom tube, designed by artist Sarah Landström, pays homage to the fly rod cases we’ve carried for generations. It’s a functional keepsake — while also built easy to recycle if you already have a hard shell you love. Inside, you’ll find a pouch and cleaning cloth made from rPET (recycled bottles), created in partnership with Keep Fish Wet. Printed directly on the cloth are the steps for better catch-and-release fishing — a reminder that keeping your gear clean and keeping fish wet go hand in hand.
