Polarized Chasm Fly Fishing Sunglasses by Marble

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. Eco-conscious polarized sunglasses designed for and rigorously field-tested by north-americanfly anglers. Featuring Zeiss sustainable lenses (50% lower CO₂) and 58% bio-based TR90 frames, Marble shades are lightweight, fog-resistant, and built for all-day wear on rivers, lakes, and flats with exceptional performance in low-light conditions. Every pair supports Marble’s mission to build a circular fly fishing economy through their fly line recycling and conservation-driven partnerships.
