Before you leave for the airport, must you wash all dishes, clean all floors, hang fresh hand towels in the bathroom and triple-check your stove’s burners to ensure they are, in fact, off? Yes? Then man, do I have the suitcase for you. It weighs just 5.5 pounds, unzips completely flat and is small enough to fit under the airplane seat in front of you. Plentiful extras include a laptop pocket, lipstick slots and a clear quart-sized toiletry pouch that clips to the inside of the bag with its own leash. Super for those who are, or aspire to be, hyper-organized.
