Balancing stylish sensibilities with outdoor expertise, the Smith Rounder ChromaPop Sunglasses are the perfect option people who split their time between the city and the wilderness. Their shape is inspired by vintage alpine sunglasses, so they feel at home in the mountains, but with a contemporary update that won't make them seem out of place at an outdoor concert or brewpub patio. Evolve frame material keeps them extremely lightweight for active comfort, and hydrophilic nose and temples pads prevent them from slipping when you're working up a sweat on the trail. ChromaPop lenses enhance contrast and make colors pop to enhance your enjoyment of stunning skylines and majestic mountain vistas alike.
