If your weekends are a mix of thrill and chill, the Smith Emerge has the range to keep up. With no-slip nose pads, these sunglasses stay put through runs and SUP sessions without the wraparound style of straight-up performance eyewear. The rectangular, bio-based frames are relaxed at the edges, giving them a refined shape that flatters most faces. They come with your choice of standard Carbonic lenses or Smith's color-boosting ChromaPop™ polarized lenses.
