Actually it does get bigger, the 4-Wheeled Titan Manhattan Trolley also comes in a 27" model along with some smaller counterparts in a 19" and 22" carry-on, a 20" business case and a 14" beauty case.
Whether you’ve consciously realized it or not, you can actually determine the quality of a suitcase by the mere fluidity with which it rolls, much like the value of a digital camera based on the weight to volume ratio. So besides the ultra-low weight, what makes the Manhattan such an essential piece of luggage? Well, lets just say it rolls like Paris Hilton at a MDMA R. Kelly-rave.
