If there was ever a showdown in the world of practical, travel-friendly backpacks, it would be between the Cotopaxi Allpa 35L and the Ortlieb Atrack BP. Both built to withstand the rugged demands of travel, each bag boasts its unique features that set it apart. Let’s dive into the nitty-gritty.

The Cotopaxi Allpa 35L, with its 35 liters of capacity, commands attention with its robust stature. Crafted from 1680D ballistic nylon paneling, it’s a bag designed for durability. It’s slightly heavier at 1.5 pounds compared to the Ortlieb Atrack BP’s featherweight 1.3 pounds, but its size benefits travel compatibility, being friendly with 80% of airlines. A standout feature is its dedicated compartment for a 15-inch laptop, making it a great choice for digital nomads.

-   Comparison Points:
