If you think man's best friend is a dog, forget it. In an era of constant travel and late night flights, your new best friend is the Fido Bag. A playful two-in-one solution to the active person's lifestyle, the Fido Bag has a large main compartment that can function as a gym bag, carry-on, duffle, or tote. A smaller compartment at the side of the bag detaches for when you need your essentials. Both are fully lined, and the entire bag features an adjustable shoulder strap. Originally designed for the Sputnik Spacelines exhibition in Tokyo, increased demand has enabled the designers to offer the Fido Bag to everyone. For $180 USD, you can take your little buddy with you wherever you go.
