Pull on the Von Zipper Snark Sunglasses when you convince your buddies to join you on the hunt for a mystical creature you just made up. Von Zipper gave the Snark sunglasses polycarbonate lenses to enhance clarity and block UV rays as you traipse through the jungle, thimble in hand, and half drunk on hope. The nylon grilamid frame withstands the epic battle with the beast, and it looks sweet in the after-photo.
