These Smith Boomtown sunglasses are built for an active lifestyle. They feature a full-coverage shield lens that wraps around for maximum protection from sun, wind, and debris. The frame is made from Evolve bio-based material – lightweight, durable, and eco-friendly. The lenses are ChromaPop polarized, which means they enhance contrast and colors while cutting glare, so you see details clearly (perfect for fishing or driving). They have an anti-smudge and moisture-resistant coating for easy cleaning. The Matte Tortoise color with Opal Mirror lens looks stylish on or off the trail. AutoLock hinges make them easy to put on with one hand. Includes a microfiber pouch for storage. Unisex fit, one size fits most. Ideal for running, biking, hiking, fishing, or just everyday wear. Smith is a trusted brand from day one.
