The Notabag is a bag and back pack in one – and the best example of the fact that really sophisticated ideas often look very simple. This bag only needs one handle to have it exactly the way you need it: around your shoulder, on your back or in your hand. It's also waterproof and includes an integrated pocket for your wallet and other treasures. And when you're not using your Notabag, it folds into a handy little pouch. This is what real flexibility looks like.
