On the outside, Hardigg's Storm Case iM2500 and New Utility Organizer is an unbreakable, water-tight carry-on case designed for easy air travel. Inside, it's an ATA-approved utility organizer in full compliance with the federal 3-1-1 regulations that governor air transportation. Together, the iM2500 and organizer offer complete protection for all carry-on contents, including clothes, laptops and more, while providing all the convenience of flight-ready luggage. Multiple pockets store papers, plane tickets, 3-1-1 regulated liquids and keep small electronics such as iPods and cameras safely separated. The Utility Organizer slides neatly into the iM250's lid, which closes to surround contents with an impenetrable, indestructible shell.
