This ingeniously designed suitcase holds up to 20% more than other carry-ons of the same size. Expansion capability and a compression panel to maximize space means you can add up to three days' worth more of clothes. Outfitted with a TSA-approved lock, an adjustable aluminum handle and silent-glide wheels, the suitcase makes negotiating the airport or train station a breeze. The luggage is made of durable polycarbonate, constructed with microwelding and a ridged design for extra strength, and rigorously tested to stand up to the demands of travel.
