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:

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.
