Part of our Nature Line, a portion of the profits from the sale of these kites is donated to NABU to support its numerous environmental projects. The Nature Line Pocket Sleds are constructed with a ripstop-polyester sail, and come with a picture of one of the animal species NABU works to protect imprinted on it. They are easy flyers, look great, and shows your support for the environment. 33x13in. (4-24 mph.) includes line, winder, and storage pouch.
