The interior and exterior fabric used to create this eco-friendly Mandrill backpack (Olive) is derived from 100% post-consumer recycled plastic bottles. The Mandrill backpack, named after the world's largest species of monkey, is earth-friendly and versatile enough for school, sport, or travel. It features plenty of room to stow your sweatshirt under the exterior cord, your laptop in the separate access garage (fits up to a 15.6 inch laptop), your notebooks or texts in the large mid-section and your smaller items in the front pocket. The two side pockets are perfect for bottles or cell phones as well. For comfort, air mesh straps with an integrated handle make this backpack easy to carry by hand or on your shoulders.
