The Cotopaxi Allpa 35L and the Boundary Supply Prima are two backpacks that manage to hold their ground in an oversaturated market. With their unique features and practical designs, they both make a pitch for the top spot of ideal carry on bags. Let's break down their individual strengths and see how they compare.

The Cotopaxi Allpa 35L, as the name implies, boasts a hefty 35L storage space. It's worth mentioning the weight - barely tipping the scale at 1.5 pounds, making it a lightweight option. Despite its capacity, the Allpa 35L stands at 20 inches tall, maintaining a compact frame which makes it a perfect companion for both occasional hikers and seasoned travelers. Its 1680D ballistic nylon paneling offers not just a sleek look but also durability, upping the longevity game, and compatibility with 80% of airlines' carry-on measurements, providing convenience. The Allpa 35L has a well-designed laptop compartment that fits up to a 15-inch laptop. Reviewers have hailed this bag as intuitive, comfortable, and perfect for minimalist travelers.

On the other side of the ring, we have the Boundary Supply Prima. With a depth of 18 inches, it's slightly narrower than the Allpa 35L. However, it towers at a magnificent 53 inches, providing extra storage and more packing possibilities. Surprisingly, it weighs virtually nothing, according to specs. Versatility is also on offer, with its 500D Kodra NylonYKK StormGuard material which provides a robust and waterproof barrier. The Prima has a laptop pocket that can comfortably host a 17-inch device. Like the Allpa, it also has broad compatibility with airlines, at about 80%. Reviewers have praised the backpack for its innovative design and functionality, dubbing it one of the best modular camera backpacks.

Here's a summary of the differences:

-   The Cotopaxi Allpa 35L has a 35L capacity while the Boundary Supply Prima holds 25L
-   The Cotopaxi Allpa 35L weighs 1.5 pounds, while the Prima weighs 0 pounds
-   The Allpa 35L is made from 1680D ballistic nylon paneling, whereas the Prima is made from 500D Kodra NylonYKK StormGuard
