The Low Gravity Day Fort Knocks are the perfect pair to take on your next climbing trip (even if that's just to your local gym). A collection of red, yellow, blue, and green climbing holds are bolted to a gray granite base, working their way across the front frame and down each arm like a cascade of freshly set routes. Silver detailing and polarized sky blue lenses round out this super-wearable pair. Designed on our durable and high-quality Fort Knocks frames, these sunglasses have a slightly wider fit than our other frame styles and provide full UV400 sun protection. Every pair comes with a climbing rope microfiber protective pouch and holographic numbered edition card.
