It's versatile enough to be compatible with almost half of the airlines in operation, a huge feat. Plus, it has a laptop compartment that can house a 1-inch laptop snugly. Many users laud the Porter for its durability, spaciousness, and the convenience offered by its clamshell opening.

Here is a brief summary of the noteworthy differences between the two:

-   The Osprey Porter 46 measures 23x36x56 inches, while the Eagle Creek Caldera™ Travel Pack 45L weighs in at 28x56x36 inches

The Eagle Creek Caldera™ Travel Pack 45L is a more environmentally-friendly option, made using high-quality 600D CORDURA® ECO Ripstop 100% Recycled, and 1200D CORDURA® ECO 100% Recycled Polyester.
