Ladies and gentlemen, allow me to introduce the Osprey Porter 46 and the Boundary Supply Errant X-Pac - two upper-tier carry on backpacks that are designed to make travel straightforward. For the wanderer, the backpacker, or the go-getter, these two backpacks tout a series of compelling features. The Osprey Porter 46 capitalizes on sheer volume with a capacity of 46 liters, the titanic of our comparison, but gives a nod to flexibility with the ability to cinch lower for a more minimal profile. Its nylon construction provides reliable endurance while its laptop compartment is best suited for smaller devices.

The Boundary Supply Errant X-Pac, on the other hand, is a smaller, sleeker puppy. It only has 22 liters of capacity but sports some noteworthy details. Made of X-Pac, it offers a lightweight yet durable structure and surpasses Porter 46 in terms of airline compatibility with a whopping 83%, thereby displaying greater flexibility for venturers. The cherry on the cake is its competent laptop compartment which can accommodate up to a 17” laptop.

In conclusion, which backpack wins comes down to your specific needs. You need to put the premium on either size or flexibility. The Osprey Porter 46 seems to be the choice for those who need to carry 'home' with them, with great organization and bulk capacity, coloured by a certain old-school backpacker aesthetic. Its compression strap keeps everything neat as a well-buttoned suit. Meanwhile, the Boundary Supply Errant X-Pac scores high with the urban traveler thanks to its excellent airline compatibility and a more streamlined and lightweight design. Choose your travel companion wisely.
