Mixtapes, music videos, and big hair. Head back to the future with the 80s feel of these Smith XC sunglasses from our 1983/84 Collection. The retro vibe lives on with a flip-up lens and heritage styling dating back to the Smith Cross-Country sunglasses. ChromaPopT lenses make sure the future is sharp, with contrast and color-boosting optics. Acid-washed jeans and neon jackets, optional.
