The Eagle Creek 2 in 1 BackpackDuffel converts from a pack to a carry on sized duffel bag with 15% more room so you can pack all the goodies you collected during your trip. As a backpack, the Air Mesh shoulder straps make sure you don't end up with a sweaty back when you dash from the cab to your flight, and padded handles make for comfortable carrying when you convert this pack into a duffel. Eagle Creek made this convertible pack mostly out of silnylon ripstop to keep it light, but strategic nylon ripstop reinforcements are sure to keep it strong for a long time. Color coded webbing loops and clips make conversion as simple and quick as can be, and the zipper to the main compartment features lockable, finger friendly zipper pulls for your security and convenience. The BackpackDuffel also features top loading and front access points so you can get to your gear whether it's a backpack or a duffel. The removable Pack in pocket keeps your essentials close at hand wherever you go, and the zippered stash pocket lets you get small items quickly. Two exterior side stretch pockets store bottles of water when you reach your destination, and compression straps with multiple lash points keep everything snug, secure, and ready for travel.
