A few specific attributes set this bag apart from its peers: One, it folds almost flat when not in use. (Ideal for city dwellers.) Two, it's super lightweight at just 7.3 pounds. Three, it has four wheels on the bottom instead of two, making navigation a breeze. (No awkward tipping.) And four, it's affordable. ($219 retail for the 20-inch carry-on size, on up to $299 for a 30-incher.)
An added bonus? It comes in four mod colorways, in addition to neutral black and brown.
