The Cotopaxi Allpa 35L and the Aer Flight Pack are both exceptional carry-on backpacks, each offering a unique set of features designed to satisfy the diverse needs of travelers. Let's consider the Cotopaxi Allpa 35L first. This backpack cuts an impressive figure in terms of dimensions, boasting a height of 20 inches, a width of 30 inches, and a depth of 51 inches. Although it weighs a little heavier at 1.5 pounds, it compensates with a significantly larger capacity of 35 liters. A top-rated choice for most airlines with a compatible rating of 80%, the Allpa 35L is made of durable 1680D ballistic nylon paneling and is also fitted with a laptop compartment that snugly fits a 15-inch laptop.

In contrast, the Aer Flight Pack may seem compact with its 49-inch height, 33-inch width, and 14-inch depth, but it is lightweight at 1.3 pounds, thanks in part to its 1680D Cordura ballistic nylon construction. The backpack's capacity of 23.6 liters may lean on the smaller side, but it compensates with its wider compatibility with a whopping 98% of airlines. Also notable is its roomy laptop compartment that can house a 16-inch laptop comfortably.

Cotopaxi Allpa 35L has received rave reviews from travellers for its efficient internal organization and comfortable shoulder straps, hip belt, and adjustable sternum straps. Additionally, inclusions like a rain cover, collapsible mesh laundry bag, nylon shoe bag, and a mesh water bottle sleeve add on to its high appeal. On the other hand, the smaller, lighter, and more airline compatible Aer Flight Pack is perfect for travellers who love staying light, mobile, and versatile without sacrificing the essential features of a reliable carry-on backpack. In conclusion, both the Cotopaxi Allpa 35L and the Aer Flight Pack offer compelling cases as the perfect carry-on backpack based on what the traveler values most, making this competition a tough call!
