Mountain biking, fly fishing, summer concert series, hiking and camping--basically, the Smith Envoy Polarized ChromaPop+ Sunglasses have you covered for all your summer activities, thanks to their lightweight comfort, precision optics, sporty wrap, and wide field of view. ChromaPop+ lenses deliver the vivid colors and high contrast of standard ChromaPop lenses, with the addition of sharper visual clarity and a lighter feel. The semi-rimless design further lightens things up while opening up a wider field of vision so you don't miss a thing, and hydrophilic nose and temple pads keep them from slipping during high-intensity activities and sweaty sessions.
