The rhino isn’t an animal to be messed with, and neither are the Rhino Fort Knocks. A distinct pattern of roughly crisscrossed wrinkles wraps the exterior in a dark, textured gray, while the interior of the frame is a smoky, frosted slate. Midnight graphite lenses and polished silver hardware give this pair the majestic finish it deserves.

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 San Diego Zoo rhino pouch.
