"I love this bag. It is the most versatile bag I have ever owned. It goes from a wheeled peice of luggage to a backpack in the blink of an eye." How's that for a customer review? A wheeled duffel with a zip-off day pack and features galore, this bag will meet most of your needs almost anywhere. We can't vouch for the performance of the wheels on backcountry portage trails (!), but this thing is about as rugged, functional, and attractive a carrier as you can find.
