For travelers and daily commuters, a great backpack is essential. Enter our contenders: the Greenroom136 Rainmaker and the Boundary Supply Prima. Both stellar options, the Greenroom136 Rainmaker stands a bit shorter and narrower but boasts deeper dimensions (40x28x21 inches) compared to the Prima’s height and width advantage (53x31x18 inches). The Rainmaker is also a tad heftier at 1.7 pounds compared to the featherweight Prima, but edges out on airline compatibility, scoring a full 100% to Prima's 80%.
Aesthetics aside, both give serious thought to organization and durability. The Rainmaker is a workhorse, crafted with 1000D Cordura and accommodating a tidy 15-inch laptop in its dedicated compartment. The Prima, on the other hand, is made of 500D Kodra NylonYKK StormGuard for an added layer of weather resistance, offering a slightly heftier capacity at 25 liters and a laptop compartment roomy enough for a 17-inch beast.
