If you're going on an adventure, you'll need Eagle Creek's Gear Hauler. This carry-on sized bag easily converts from a duffel to a backpack with zip-away backpack straps, an over-the-shoulder handle and grab handles. Add to that the durability of water-repellant, travel abuse-resistant Bi-Tech fabric and bottom bathtub construction that's water resistant. This super-light bag also features a 15" laptop and tablet sleeve and front pocket organization that includes a key fob with Porter Key bottle opener. Additionally, includes an end compartment for organization, unique cord winder to avoid tangled cords and compression straps and external lash points for securing gear. Plus you don't have to worry about security with the puncture-resistant #10 lockable zippers and Central Lock Point for securing the bag closed with a single lock.
