Marble – CHASM Polarized Glasses

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.
