Both the Cotopaxi Allpa 35L and the Cabin Zero Classic Plus 42L are the solid companions you want on your back when embarking on your next adventure. They don't differ much in height but the extra width and depth of the Cabin Zero allows for an additional 7 liters in capacity. Obviously, extra storage means extra weight, right? No, not in this case. The more capacious Cabin Zero comes in at 1.175 pounds, lighter than the 1.5 pound Cotopaxi Allpa.

Here's a simple breakdown of your options:

While both bags have similar positive reviews, the Cotopaxi seems to impress travelers with its smart design, intuitive organization, and durable construction. It also has a few additional features that set it apart from the Cabin Zero, such as the rain cover and included accessories like the collapsible laundry bag and shoe bag.

On the flip side, the Cabin Zero is preferred by those who need to carry more gear. It seems to hold quite a lot for a carry on, even a week's worth of essentials according to some users. It is also applauded for its comfort and ease of storage, thanks to its stowable straps.

To cap this off, there's no wrong choice here. If you're a light and smart packer, go for the thoughtfully designed Cotopaxi. Yet, if your travels require more capacity and you're concerned about comfort and convenience, the money's on the Cabin Zero Classic Plus 42L. Both promise durability and airline compatibility, so really, the choice comes down to your personal travel style.
