There's a time and a place to sweat the details. Designing the Riptide, we did just that. These Smith sunglasses are a classic, Italian-made style with bio-based frames. Spring hinges expand the fit at the temples. The extra flex is not only more comfortable, but feels snug through runs and bike rides. These glasses come in two lens options, each with glare-cutting polarization. ChromaPop™ lenses boost detail, color and clarity while ChromaPop™ Glass has the added benefit of high scratch resistance.
