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. Sustainable Build Frames made from 58% bio-based materials, lenses with 50% fewer carbon emissions. Featherweight Balance Designed to be your new eyes, CHASM features a full wrap design that effortlessly floats on all face shapes and fits with your favorite fishing cap. Water & Fog Resistant Zeiss Polarized lenses, treated and tested for river glare, wet and humid conditions. Guide-Tested Performance Designed by and for fly anglers, with field feedback from 15+ guides across Canada and the US.
