Examining the Greenroom136 Rainmaker and the Ortlieb Atrack as carry-on backpacks offers an interesting look at two distinct approaches to design. First up is the Rainmaker. This monster stands tall at 40 inches with a depth of 21 inches. It's a sizable beast perfectly suited to the traveller looking for durability. It's constructed out of tough 1000D Cordura, and comes equipped with a laptop compartment accommodating up to a 15inch laptop. The carry-on compatibility clocks in an impressive 100%. It definitely prioritizes function over form. Reviewers have noted its sturdy nature, praising its value on the market, and claiming it's great for everyday use, especially if you're carrying electronic devices.

Alternatively, the Ortlieb Atrack boasts a very different set of charms. It is a smaller pack, standing only 5 inches tall with a depth of 56 inches. Yet, it manages to surpass the Rainmaker in terms of capacity, boasting a spacious 25 litres. It's lighter as well, weighing just 1.43 pounds compared to the Rainmaker's 1.7 pounds. It is constructed out of PS33, and comes with a laptop compartment that unfortunately has no capacity for laptops. Though it is only compatible with 47% of airlines, it impresses with its versatility. The Ortlieb Atrack shines as a waterproof option that's great for adventurous environments. Reviewers praise it as ideal for wet conditions and love its accessibility, calling it a comfortable and durable travel tool.

To summarize, the differences look like this:

Considering the Greenroom136 Rainmaker and the Ortlieb Atrack, the former is the choice for rugged functionality, while the latter impresses with its waterproof design and comfort. Both backpacks offer distinct advantages and cater to different traveller's needs. One is not universally 'better' than the other. Evaluate your priorities, weigh them against the benefits of each individual backpack, and make your choice. While the Rainmaker comes with more customizability options and a water-resistant exterior featuring a lot of organization, the Atrack is noted for its comfortable support, weatherproof design, and availability in different sizes. Choose accordingly!
