  • Features

    • Ellume Polarized lenses offer crisp, high-purity optics that control for specific wavelengths of visible light so you see colors more vividly and with greater depth perception
    • Lenses are made from Z-Resin, a durable plant-based material derived from the castor plant; Z-Resin reduces the amount of C02 produced during manufacturing
    • Scratch-resistant hardcoat and impact-resistant lenses are ideal for outdoor activity and longevity
    • Polarized lenses decrease eye strain by reducing visible glare from water, snow, sand and pavement
    • 95% High-Energy Visible (HEV) light reduction promotes clarity
    • 100% UV protection from the sun's harmful rays
    • Durable See Grass frames are manufactured from recycled plastic and agricultural grasses using renewable energy
    • ProFlex rubber on the nose and temple tips provides a soft and comfortable hold while keeping sunglasses in place no matter what the day brings
    • For every pair purchased through REI, a tree will be planted in our national forests in conjunction with the National Forest Foundation and 1% for the Planet
