From rhinos to raccoons, birds to bees, and humans to hermit crabs, we’re all part of the Animal Kingdom. But some of us are doing a lot better than others. We don’t want our friends to go the way of the woolly mammoth, so Knockaround has partnered with San Diego Zoo Wildlife Alliace to lead the fight against extinction.

Through 2021, $5 from every pair sold from our San Diego Zoo special release collection will go to support the San Diego Zoo Wildlife Alliance, to help protect species and their habitats worldwide.

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.
