Both the Osprey Porter 46 and Patagonia Altvia Pack 36L are reliable options when it comes to durable and reliable carry-on backpacks. The former's Nylon material provides rugged durability, while the latter's recycled nylon ripstop enhances its eco-friendliness without compromising sturdiness. Your laptop will have to stay behind with the Altvia pack as it lacks a laptop compartment, quite the opposite of Porter 46's spacious 1-inch laptop holder.

Here's a glory shot on how these two bags size each other up:

When it comes to personal preference, the Osprey Porter 46 is a sturdy keeper with a remarkable suspension system. It can easily double as plush storage for your gear or compact duffel thanks to its spacious interior and unassuming elegance. The Patagonia Altvia Pack 36L, on the other hand, is for conscious outdoor lovers looking for a light yet truly functional pack. It offers extraordinary external attachments, comfortability, and the assurance that its manufacture didn't harm Mother Nature—every bit counts.

So, what's the verdict? For those leaning towards practicality and versatility, the Osprey Porter 46 is a sure bet. Its ample space, ability to accommodate a laptop, and compatibility with a broad range of airlines makes it a prime choice. Yet, if eco-friendliness and intuitive outdoorsy features are your thing, the Patagonia Altvia Pack 36L is your match. Despite a smaller size and fewer airline compatibility, the featherweight factor and its motivation to conserve resources cannot be overlooked. What tips the scales for one might sink the boat for another—it all depends on what you as the user values most.
