It all begins high in the Rocky Mountains. At the headwaters of the Colorado River lies a magical stretch of water that stretches through the desert, creating the landscapes that have drawn explorers for centuries to wonder at the power of this river to shape lives and landscapes. Before the snowmelt and rains of the high-country slip onto the Colorado Plateau, they run by Radium Hot Springs, long touted for its healing properties, Radium has become a destination for adventure seekers, fishers, rafters, kayakers and cliff jumpers. Inspired by this special place, Zeal Optics RADIUM sunglasses are your partner in the search for what’s around the next bend, and for kicking back and relaxing in your favorite spots.

RADIUM features a 6-base, triple injection plant-based Z-Resin frame with ProFlex Rubber on the nose to keep your shades in place wherever you find yourself. With clean lines and soft styling, RADIUM moves with confidence and comfort.
