Backpacks have been with us for centuries. With school and everyday life, most needed one at some point. Baggu is a company that specializes in bags that are really inexpensive and are all made of recycled materials. Their backpack can be used “for books, a laptop, they gym or [as] an overnight bag,” and offers a magnetic snap, buckle closure, interior pocket and adjustable shoulder straps. They used a “16oz recycled cotton canvas” which makes for a pretty sturdy bag. They’re available at Baggu.
