The Eco Wanderer is American Tourister's first environmentally friendly collection. The inner and outer material is made from recycled PET bottles. They're sturdy, flexible, and durable. In addition, the collection is equipped with new spherical wheels for extra rolling comfort. Another feature is the extra zipper with which you increase the luggage space. That's convenient! The suitcases are also equipped with a secure TSA lock and a front pocket to store important travel documents.
