When it comes to carry-on backpacks, the Cotopaxi Allpa 35L and REI Co-op Ruckpack 28 stand toe-to-toe. Taking the Allpa 35L for a whirl, we know it measures up at a sturdy 20 inches tall, 30 inches wide, and 51 inches deep, with a corresponding capacity of 35 liters - more than enough room for a weekend getaway. Plus, it accommodates a 15-inch laptop and offers a number of attractive features, like its 1680D ballistic nylon paneling and extras including a rain cover, a collapsible mesh laundry bag, and a comfortable shoulder and hip belt system.

Switching gears to the REI Co-op Ruckpack 28, its dimensions come to 51 inches' height, 28 inches' width, and 26 inches' depth, offering a roomy capacity of 28 liters. Made from tough 210-denier nylon ripstop, it's a tad lighter than the Allpa at 1.2 pounds. Still, it doesn't compromise on accommodation, providing a laptop compartment for 15-inch models. Moreover, its compatibility with 92% of airlines beats out the Allpa's rating of 80%.

To cap it off, the Cotopaxi Allpa 35L seems to be a hit with reviewers, who commend its intuitive internal organization and durability. However, the price is slightly higher, which might be something to consider. The Ruckpack 28, on the other hand, is a high-performing carry-on backpack designed for both urban and adventurous travels. Its lighter weight and superior airline compatibility give it an edge. Overall, the choice between the two comes down to personal needs and preferences. Both options are solid for any seasoned or budding traveler.
