The F13 Top Cat messenger bag design by Freitag wins awards for both style and sustainable living. How many tires do you throw away in a lifetime? How many seatbelts have you worn? These bags are made of materials from both, recycled into this excellent line in the variety of shapes and sizes shown here. You can even design your own bag instead of choosing one of these! The Top Cat is rugged; it’s both water AND messenger-proof. It holds a Macbook when unextended, and Freitag claims the extended version can hold a small human. If you find out if this is true, we don’t want to know.
