If you're in the market for a reliable travel backpack, the Cotopaxi Allpa 35L and the Deuter Trans Alpine 28 SL are two options worth considering. Both bring their unique strengths to the table. Constructed with robust 1680D ballistic nylon paneling, the Cotopaxi Allpa 35L is designed for durability and boasts an intuitive internal organization that can hold up to the rigors of travel. It is larger than its counterpart, offering a capacity of 35 liters as opposed to the Deuter's 28. It can comfortably house a 15-inch laptop in its dedicated compartment, and the bag itself weighs 1.5 pounds.

Despite being smaller, the Deuter Trans Alpine 28 SL is not to be overlooked. It benefits from a 210D PA and 600D PES make-up, contributing to a lighter weight of just 1.19 pounds. It shies away from integrating a laptop compartment, but what it lacks in technology accommodation it makes up for the adjustability. This is particularly useful for users with a shorter stature as it is designed to be more proportionate to a woman's body size.

-   The Cotopaxi Allpa 35L has a greater capacity than the Deuter Trans Alpine 28 SL (35L vs 28L)
-   The Cotopaxi Allpa 35L is heavier than the Deuter Trans Alpine 28 SL (1.5lbs vs 1.19lbs)
-   The Cotopaxi Allpa 35L has a laptop compartment while the Deuter Trans Alpine 28 SL does not
-   The Cotopaxi Allpa 35L is compatible with 80% of airlines while Deuter Trans Alpine 28 SL is compatible with 65% of airlines
-   The materials used in both bags vary, with Cotopaxi Allpa 35L consisting of 1680D ballistic nylon paneling, and the Deuter Trans Alpine 28 SL consisting of 210D PA, 600D PES.

Despite the differences, both bags have received positive reviews from users and rank highly for their quality and durability. One customer expressed surprise at the effectiveness of the Cotopaxi Allpa 35L's internal organization, calling it perhaps "the best configuration I’ve used so far". This backpack also includes a rain cover for added protection and added elements such as a collapsible mesh laundry bag and a nylon shoe bag.

On the other hand, the Deuter Trans Alpine 28 SL, while lacking in some elements, is praised for fitting women's body sizes better, something that the standard sizes often disregard. As such, it all comes down to personal preference as both bags offer unique features and strengths.
