If you're on the lookout for a reliable and sturdy carry-on backpack for your next adventure or for a practical everyday use, two that should definitely be on your radar are the Greenroom136 Rainmaker and the Osprey Flapjack.

The Rainmaker by Greenroom136 is a solid and function-focused backpack. Weighing 1.7 pounds, it's slightly heavier than the Flapjack, but it makes up for the extra weight with its rugged 1000D Cordura construction. The Rainmaker also offers 22 liters of storage capacity and a laptop compartment that can comfortably fit a 15-inch laptop. Reviewers sing praises of its sturdiness, versatility, and customizability. According to one, "Overall, it’s a solid pack that values function above all else. And all of the customizability options are incredible."

In comparison, the Osprey Flapjack, lighter at 0.9 pounds, this backpack holds similar bells and whistles. It offers a capacity of 21 liters and, like the Rainmaker, it can stow away a laptop of up to 15 inches in its designated compartment. The Flapjack, however, falls short in its construction material which is 600D Polyspun – a step below in terms of durability than the Rainmaker robust 1000D Cordura.

To summarize the main differences:

-   The Greenroom136 Rainmaker is slightly taller and wider, but not as deep as the Osprey Flapjack.
-   The Rainmaker is heavier, but also has a larger capacity.
-   The Rainmaker utilizes 1000D Cordura, making it sturdier than the Flapjack's 600D Polyspun material.
-   In terms of airline compatibility, the Rainmaker has a slight edge over the Flapjack.

On the flip side, the Osprey Flapjack, as the reviewers also note, is indeed one of the best value bags on the market. The lower weight, combined with its size, makes the Flapjack a worthy contender to the Rainmaker. If weight is a priority for you, the Flapjack might just be the way to go. However, if you can bear a slightly heavier backpack for better durability and slightly larger capacity, the Rainmaker should be at the top of your list. Each of them have their own strengths, the final decision should be based on your personal preference, needs and budget.
