It's pretty comical that the four corners monument isn't located at the exact spot that Utah, Arizona, Colorado, and New Mexico meet; since you're a bit of a perfectionist, you prefer finding the real location with the help of a GPS and Smith's Landmark Sunglasses. This Landmark features Chromapop lenses that filter out crossover colors to make the blue sky and orange desert really pop. Smith polarized these impact-resistant lenses to cut out the glare so you can use the GPS without eye fatigue, and the lenses contain various treatments to resist reflections, oil smudges, and water. The Evolv frame features bio-based materials for an environmentally-friendly construction, and the metal bridges maintain a solid structure for durable longevity.
