The Osprey Porter 46 is a rugged contender in the carry-on backpack department - a hearty combination of capacity and sturdiness. Despite its hefty dimensions of 23 by 36 by 56 inches, it is light for its size, tipping the scales at 1.5 pounds. Nylon construction ensures durability, helping the bag stand up to heavy use over time. The Porter successfully balances volume with ease of use, boasting 46 liters of capacity and a 47% compatibility rate with airlines. Handy features such as a laptop compartment suitable for a 1-inch device and various handles enhance its appeal for travelers who require versatility with high baggage load.

Enter the Atom Pack "The Mo," nearly skeletal in weight and bulk compared to the Porter. Despite its larger dimensions of 74 by 84 by 91 inches, this carry-on is a featherweight - weighing an astounding 0 pounds. Constructed from the resilient VX21 X-Pac fabric, it manages to combine solidity with a paltry mass. At 40 liters, "The Mo" offers slightly less carrying capacity than the Porter but compensates with a unique customizable design on its website. However, its airline compatibility falls short at 19%.

Comparison Bullet Points:

The Osprey Porter 46 has garnered significant acclaim from reviewers stating, "For better or worse, the Osprey Porter 46 is a big pack with a big capacity." It offers excellent suspension and stands out for its ample space, handy clamshell opening, compression strap, and overall lightweight nature. Even Osprey's own company labels it as an "impressive gear-hauling travel backpack."

On the flip side, The Mo by Atom Packs has been a game-changer for one reviewer who proclaimed it to be "both the comfiest and the lightest pack I’ve ever used." While it sports abundant lash points and secure, comfortable hip straps, its standout feature is its incomparable lightweight build. In summary, each bag offers unique selling points to discerning travelers, whether it's the spacious and sturdy Osprey Porter 46 or the ultra-lightweight and customizable Atom Pack "The Mo."
