Practical Hacks Kevin has a terrific review of a new ultralight roller (see video below):
If you survey the marketplace for lightweight, wheeled carry-on bags – defining lightweight as less than 5½ pounds (2.49 kg) – the landscape isn’t exactly cluttered. A Saks offers a 4.8 lb. wheeled duffel, Travelite offers a “Starlight” wheelie that checks in at 5.07 lbs (2.3 kg) but is only available in Europe, and then of course there’s the Landor & Hawa IT-0-2, which tips the scales at 5.02 pounds (2.28 kg).
