Meet your new best friend in packing. With one each of all sizes, these packing cubes will have you perfectly organized. Separate your clothing types or outfits and fill up the medium and large cubes, which are sized for packing into a carry-on with room to spare. Stash cords/loose items in the small cube, and toss it in your travel bag or personal item (it also makes a generous headquarters for travel snacks). These minimalist sanity-savers separate anything you need into neat, perfectly sized packages that slip snugly into your luggage. A mesh window lets you see inside, so you'll never again have to dig around your bag.
