The Osprey Porter 46 and the Millican The Core Roll Pack 20L are two strong contenders in the world of carry on backpacks. What stands out immediately about the Porter is its sheer size. At 46 liters, it offers over twice the capacity of the 20-liter Millican, and its dimensions - 23" tall, 36" wide, 56" deep - reflect this. While some might find such a large backpack unwieldy, reviewers consistently praise the Osprey Porter 46's excellent suspension and compression straps, lending it stability and ease of carry.

By comparison, the Millican The Core Roll Pack 20L may seem modest with its 20 liters of capacity and 13" x 29" x 50" dimensions. Where it lacks in size, this backpack strongly makes up in compatibility, suitability for most airlines (82%, compared to the Porter's 47%), weight, and sustainability. Weighing a mere 0.6 pounds against the 1.5-pound Porter, and being made from 100% recycled Polyester (RPET) 900D, the Millican is a conscious choice for eco-minded frequent flyers.

Key Points of Comparison:

When it comes to reviews, the Porter 46 is celebrated for its vast capacity and durability, manifested in its 'duffel' stature. That being said, the Millican Roll Pack appeals for its craftmanship and green thumb, being constructed entirely of recycled materials. The Core Roll Pack's compatibility with a wider range of airlines also gives it an edge for those mindful of size restrictions in air travel.

Both the Osprey Porter 46 and Millican The Core Roll Pack 20L offer features to suit different types of travelers. It's a 'big pack vs. small pack' showdown, and the right choice boils down to the user's priorities, whether it's for capacity, compatibility, lightweight nature or eco-friendliness. As is evident, both bags have rightful claims to the title of go-to carry on backpack.
