Smith Backcast Sunglasses Eyes on the Prize These frames balance the glare-cutting polarized tech you need on the water with a look that fits everyday wear. The foundation is an bio-based frame that keeps weight down without sacrificing durability. Low-profile frame details minimize moisture buildup, so water and sweat clear fast instead of pooling at the rim. Auto Lock hinges hold the frames open for easy one-hand on and off, which matters when your other hand is on a rod, a paddle, or a handlebar. Whether you're reading water from a skiff or riding home post-ride, these are a pair you'll reach for on both. Features Chroma Pop Polarized Lenses filter two specific wavelengths of light to cut glare and enhance color and contrast beyond what standard polarization delivers, so surface detail on water reads clearly Evolve Bio-Based Frame is lightweight and durable, giving you a frame that holds up to sun, salt, and daily use without adding bulk Megol Temple and Nose Pads provide non-slip grip so glasses stay put, even in heat, humidity, or sweat Leash-Ready Temple Tips accept a retention leash so the frames stay secured on and off the water, eliminating the risk of losing them overboard or on a descent6-Base Lens Curvature offers a modest wraparound fit that blocks sun and glare from the sides without the tunnel-vision feel of a full wraparound Smudge and Moisture-Resistant Coating keeps optics clear and easy to clean throughout a full day outdoors | Smith | Backcast Sunglasses Men's In Matte Black/chromapop Polarized Black
