Eagle Creek Gear Warrior 32

We have two of these, one in blue and one in yellow. Of all the flights we've taken, we've never seen another one of these popping out on the luggage carousel at the airport.

We keep the weight of each one to between 15 and 19 kilograms (33 to 42 pounds). They seem to handle that just fine (the trick is to keep them under 20 kilos, which is the cut-off point for "heavy" bag charges at many airlines). Empty, each one weighs just over 3.5 kilograms.

Each of us has three of these to put our clothes in. Color coordinated.
