The Cotopaxi Allpa 35L and the Eagle Creek Caldera™ Travel Pack 45L are both high quality carry on backpacks, but they offer different advantages based on your specific travel needs. The Cotopaxi Allpa 35L is a well-rounded choice ideal for both city and nature tripping. Crafted from 1680D ballistic nylon paneling, this bag has a tough, rugged durability that can stand up to intense wear and tear. Weighing in at 1.5 pounds, it provides 35 liters of packing space and is compatible with the carry-on restrictions of the majority of airlines. Reviewers applaud its intuitive internal organization making packing a hassle-free endeavor.

On the flip side, the Eagle Creek Caldera™ Travel Pack 45L is constructed from CORDURA® ECO 100% recycled materials. This makes it an attractive choice for the environmentally conscious traveler. Weighing slightly less at 1.42 pounds, it sports a greater packing capacity of 45 liters which may not be accepted as carry-on by all airlines. Its standout feature is the TripSync™ system, a tool that tracks travel miles and can locate the bag if it's lost. The sturdy build and organizational offerings win praise from users.

Here's a quick bullet-point comparison of the two bags:

The Eagle Creek Caldera™ Travel Pack 45L prides itself in its overall durability and ethical construction.
