The Granite Gear Flyer is a multi-functional campsite diversion. The Flyer is a foam disk covered with pack cloth and edged with 500-denier nylon fabric. It flies great and when you're done playing, "sit on it!" This Granite Gear trail toy makes a comfy butt pad. This disk is also great for your canine companion. It holds up far better than a plastic disk and itís a lot easier on your dog's teeth.
