First things first. The Greenroom136 Rainmaker by Greenroom136 and the Ortlieb Atrack BP by Ortlieb are two impressive carry-on backpacks. They share the style, sleekness, and elegance that a traveler or a day-commuter would appreciate, but differences in design and functionalities exist.

The Rainmaker's 40-inch height, 28-inch width, and 21-inch depth provide you with a handy backpack. However, its 1.7-pound weight can be a deal-breaker for those who prefer traveling lightweight. On the other hand, even with its spacious dimension—25 inches tall, 26 inches wide, and 56 inches deep— the Atrack BP only weighs 1.3 pounds, a haven for adventurers who need extra space but less load. Yet, pay attention to airline compatibility. Rainmaker is compatible with all airlines, while the Atrack BP only aligns with 38% of them.

Here are summarized points of differences:

Rainmaker made of 1000D Cordura, earns applause for its customizability options and function-first approach. Its 22-liter capacity, sturdy and water-resistant exterior, excellent organization features, and a laptop compartment fitting a 15-inch laptop indicate that the Rainmaker can be your right-hand for everyday commuting or even on a business trip.

On the other hand, with a capacity of 25 liters, a laptop compartment that does not fit any laptop, and construction from robust PS21R material, the Atrack BP is truly an adventure-oriented backpack. It gets kudos for its robust waterproofness, light weight, spaciousness, and adjustability. Comfortable and secure, even during a wet and cold commute, this backpack seems made for rugged outdoor travel and biking. Make your choice wisely.
