When it comes to carry-on backpacks, choosing between the solid options of the Osprey Porter 46 and the OpposeThis Invisible Backpack 3 can be a tough call. The Osprey lends itself well to the rugged urban traveler, its nylon design built for durability. It's a hefty pack with a sizable 46-liter capacity, and yet, surprisingly lightweight at just 1.5 pounds. Notable features include a laptop compartment able to store a inch and compartments large enough to swallow up all your gear. The stout value of the Osprey, however, limits its compatibility with airlines, only being suitable for 47% of them.

The Invisible Backpack 3 by OPPOSETHIS is a different beast altogether. Its stylish, understated design made from a lightweight waterproof nylon-polyester blend is both attractive and practical. At 0.9 pounds, it's lighter than the Osprey, but with a smaller capacity of 23 liters. It shines in the travel world though, being compatible with a staggering 98% of airlines. Feature-wise, it touts a laptop compartment for up to a 15 inch device, a shoe compartment, and quick-access pockets.

So, which should you opt for? If you're a heavy packer, frequenting less stringent airlines and value the ability to stuff your bag to the brim, the Osprey Porter 46 comes highly recommended. It's durable, spacious with a good suspension system that balances load easily.

On the other hand, if light travel and high compatibility are your main priorities, do consider the OpposeThis Invisible Backpack 3. It's a breeze to carry around, gently weatherproof, and its various compartments provide ample organization options. Whether for work or play, either backpack would serve you well upon different needs and preferences.
