When it comes to a good carry on backpack, two stand out among the rest: the Osprey Porter 46 and the Cotopaxi Allpa 28. This isn't your run-of-the-mill school backpack. They’re both beasts of burden tailored to handle the rough and tumble of adventure travel or the more predictable demands of modern urban commuting - whatever gets thrown at them. Before we delve deeper, let’s set a clear picture of how these two match up against each other.

  • Dimensions: Osprey Porter 46 (23x36x56 inches), Cotopaxi Allpa 28 (49x30x24 inches)
  • Weight: Both weigh 1.5 pounds
  • Capacity: Osprey Porter 46 (46 liters), Cotopaxi Allpa 28 (28 liters)
  • Airline Compatibility: Osprey Porter 46 (47%), Cotopaxi Allpa 28 (92%)
  • Material: Osprey Porter 46 (Nylon), Cotopaxi Allpa 28 (TPU-coated 1000D polyester 1680D ballistic nylon paneling)
  • Laptop Compartment: Osprey Porter 46 (fits a 1-inch laptop), Cotopaxi Allpa 28 (fits a 15-inch laptop)

Think of the Osprey Porter 46 as the pack mule of backpacks. It's got a bigger build, an impressive 46 liters of space ready for your stash. It's made from durable nylon and it can easily accommodate your gear whether bulky or slim. One reviewer put it succinctly, "The Osprey Porter 46 is an impressive gear-hauling travel backpack. Bulk it up or cinch it down, the Porter is a durable option for those who tend to carry more."

Alternatively, the Cotopaxi Allpa 28 might be smaller in size, but it punches above its weight in terms of overall quality and thoughtful design. It’s compatible with a large number of airlines and shines when it comes to the material - a tough TPU-coated 1000D polyester with 1680D ballistic nylon paneling. It's also water-resistant, and its construction allows easy access to your gear. One reviewer raved, "The Cotopaxi Allpa 28L Travel Pack is a tough, adaptable travel bag that can venture into urban and more rugged outdoor environments alike."

Make no mistake, both backpacks are sturdy and reliable options. But when choosing between the two, consider what you most value in a backpack. Is it capacity? Is the airline compatibility more important? Do you prefer a specific material or need a wide laptop space? In the end, choosing between the Osprey Porter 46 and the Cotopaxi Allpa 28 boils down to personal preferences, needs, and where your adventures are bound to take you.
