The Osprey Porter 46 and the Ortlieb Atrack CR Urban are two exceptional carry on backpacks that cater to different travel needs and tastes. The Osprey Porter 46 boasts a substantial 46 liter capacity, made for those who tend to carry more on their journeys. It's a nylon beast, weighing 1.5 pounds and furnished with a laptop compartment for a 1-inch laptop. This backpack is compatible with 47% of airlines, designed to stand up to any adventure you could throw at it. It's lauded for its robust suspension system, capaciousness, quick packing-and-unpacking, compression strap for a neat appearance, and its lightweight design relative to its size.

The Ortlieb Atrack CR Urban, on the other hand, is designed for urban adventurers who appreciate a blend of utility and style. While this backpack has a smaller capacity, 25 liters, and fits a laptop size of 0 inches, it doesn't hold back on quality construction. Made of the enduring PS55C and weighing 1.3 pounds, it might be slightly heavier, but it's waterproof construct is a big plus for the nomad caught in spontaneous rain showers. Moreover, it's compatible with 38% of airlines and is praised for its adjustable harness system, weatherproof build, external loops for gear, and timeless aesthetic.

Summarizing the differences:

-   **Size and Capacity**: The Osprey is larger (23x36x56 inches) with a 46-litre capacity. The Ortlieb is smaller (25x26x56 inches) with a 25-litre capacity.
-   **Weight**: The Ortlieb is slightly lighter (1.3 lbs) than the Osprey (1.5 lbs).
-   **Material**: The Osprey is made of durable Nylon, while the Ortlieb is made from robust PS55C.
-   **Laptop Compartment**: The Osprey can accommodate a 1 inch laptop, whereas the Ortlieb can't fit a laptop.
-   **Airline Compatibility**: The Osprey is compatible with more airlines (47%) compared to the Ortlieb (38%).
-   **Special Features**: The Osprey offers suspension and a clamshell opening, while the Ortlieb boasts of an adjustable harness system and weatherproof build.

The best backpack to choose will ultimately depend on individual needs. If the intent is to carry a lot of stuff, the spacious nature and clamshell opening of the Osprey Porter 46 make packing a breeze. But if edgy style and all-weather durability are what you're looking for, the Ortlieb Atrack CR Urban shouldn't be overlooked. In essence, both bags excel in their unique ways – the Osprey in its large volume and the Ortlieb in its urban aesthetic and all-weather design. Picking one would be the matter of personal preference and specific travel demands.
