When considering carry-on backpacks, size and weight are crucial factors. Both Greenroom136 Rainmaker and Attitude Supply ATD1 offer ample space. The former measures 40"x28"x21" and weighs 1.7 pounds, while the latter is slightly larger and lighter at 51"x30"x26" and 1.5 pounds, respectively. Greenroom136 Rainmaker's smaller dimensions but slightly heavier weight imply that it favorably balances capacity and sturdiness.
When examining capacity, Greenroom136 Rainmaker offers 22 liters, a fraction more than Attitude Supply ATD1's 20 liters. It is noteworthy that both can safely carry a 15-inch laptop. It's also worth noting while the Greenroom136 Rainmaker is rated to be compatible with 100% of airlines, you may experience a little more restriction with the Attitude Supply ATD1, which is only compatible with 90% of airlines.
The choice of material for the backpacks suggests a durability leaning towards the Greenroom136 Rainmaker as it's made of 1000D Cordura compared to the Attitude Supply ATD1’s 500d, PU coated Cordura with DWR. However, the latter has a water resistance feature not mentioned for the former, which could be a deciding factor depending on intended use.
Throughout their use, numerous reviewers have expressed their positive impressions of both bags. With comments about Greenroom136 Rainmaker's function-over-frills design and Attitude Supply ATD1's value for money, hardy construction, and versatility, it's clear that both carry-on backpacks offer their unique selling points.
