Smith Lowdown XL 2 Sunglasses Eyes on the Prize Chroma Pop lens technology is the reason riders reach for Smith glass on the road and trail, and the Lowdown XL 2 puts that same optical performance in a lifestyle frame sized for larger faces. The Evolve frame incorporates bio-based material into an injected-polymer construction that keeps weight down without sacrificing durability. Megol gel nose pads grip your skin gently and grip harder as moisture builds up, so the frame stays put whether you're on the bike or off it. Auto Lock hinges hold the frames open for easy one-hand on and off, a small detail that adds up on long days. If your face has always been a half-size too big for the standard Lowdown 2, this is the version that fits. Features Chroma Pop Lens Technology filters two specific wavelengths that cause color confusion, delivering more detail through greater definition, more natural color, and unmatched clarity Evolve Bio-Based Frame made from a bio-based polymer containing a minimum of 55% castor oil, offering the same performance and durability as nylon Megol Nose Pads provide a hydrophilic grip that gently holds the frame in place and increases grip when introduced to moisture Hydroleophobic + Anti-Reflective Lens Coatings cut glare and resist water and oils for clean optics in variable conditions | Smith | Lowdown Xl 2 Sunglasses Men's In Matte Black/chromapop Photochromic Brown | Nylon
