The Osprey Porter 46 is a versatile carry-on pack designed for individuals who carry more on their travels. With its dimensions at 23 inches tall, 36 inches wide, and 56 inches deep, it offers a large 46 liter capacity while staying lightweight at 1.5 pounds. Its nylon construction ensures durability, and savvy travelers will appreciate the laptop compartment sized for up to a one-inch laptop. However, it falls short with airline compatibility, fitting within the carry-on restrictions of only 47% of airlines.

The Attitude Supply ATD1, on the other hand, is a lean but substantial counterpart. Measuring 51 inches tall, 30 inches wide, and 26 inches deep, its 20 liters capacity may seem smaller, but it shares the same 1.5-pound weight as the Osprey. It surpasses its rival with a laptop compartment that fits a 15-inch laptop and the compatibility with an impressive 90% of airlines. Crafted from 500d, PU coated Cordura with DWR, it promises durability and longevity.

Here's a short bullet point comparison to enlighten further:

-   The Osprey Porter 46 has a large 46 liters capacity versus the Attitude Supply ATD1's smaller 20 liters.
-   The Porter 46 offers a laptop compartment for up to a 1-inch thick laptop, while the ATD1 can accommodate a 15-inch laptop.
-   The Osprey model falls short in airline compatibility at 47% while the ATD1 comes ahead at 90%.
-   The Porter 46 is constructed with sturdy Nylon, while the ATD1 is made with durable, water-resistant 500d, PU coated Cordura with DWR.

Reviewers have praised the durability and versatility of both packs. The Porter 46 comes highly recommended for its overall value, excellent suspension, spaciousness, clamshell opening, and compression strap that prevents the bag from looking sloppy. It's seen as a robust choice for urban travelers. On the other hand, the Attitude Supply ATD1 gets acclaimed for its versatility and adaptability as a convenient everyday carry-on and travel pack, with bonuses like expanded capacity, convenient rolltop, clamshell opening, organized front pocket, and secure laptop compartment. The deciding factor often boils down to individual preference on space and airline compatibility.
