Hefty baggage fees are one of the worst parts about air travel–one pound over the limit and you could be out $100. That’s why engineer John Power invented JakToGo, a wearable solution to help airline passengers beat the baggage charges. Although this lightweight jacket won’t be flattering to your figure, JakToGo can save you some serious cash by storing up to 10kg of extra baggage in its numerous pockets. After you’re through the airport checkpoints, you can also fold the jacket up and carry it as a shoulder bag.
