Best Travel Backpacks

I evaluated 10 packs that can be stuffed under the seat in front of you on most airlines. The best of them do double duty as daypacks once you land, too.

According to United Airlines, I have over 700,000 lifetime miles aboard their aircraft. Most of them have not been for pleasure, alas, but for work as a freelance journalist. 

If there’s any benefit to all those hours (months? years!) flying, it’s knowing how to pack and what to bring. Rule No. 1: Merino wool, because it’s comfy, not scratchy, and doesn’t retain body odors, which is key because the clothes you pack probably won’t see a washing machine for a while. Rule No. 2: Lay everything out beforehand. This allows you to “edit” what you pack—by sacrificing wants in favor of needs—and strategize about what to put where within your bag of choice, so it’s easier to locate that eyeshade, Nyquil, or novel when you’re exhausted and the cabin lights are out on your red-eye. 

Which brings me to Rule No. 3: Never check a bag. Ever!

That means everything you take with you should fit in two bags—a roll-aboard and a “personal item,” airline parlance for the purse, briefcase, shoulder bag, or backpack that stays with you during the flight. Pulling off proper two-bag travel requires a combination of tactical savvy and the right gear. I’ve managed trips as long as two weeks by wearing hiking boots onto the plane (so they eat less room in my bags) and taking only one other pair of footwear—running shoes, which do triple duty for exercise, daily use, and slightly more “formal” wear when matched with jeans and a blazer.

As for the gear? A good roller bag is important, but it’s ultimately the personal item that can make or break your trip. That bag needs to offer maximum utility and flexibility, and to that end nothing beats a travel backpack. The genius of these bags is that they can accommodate way more stuff—and in a much more organized way—than a purse or briefcase. But some backpacks make better travel companions than others. That’s why I took a look at 10 of them. (See how I evaluated each of these travel backpacks, below.)

The Patagonia Black Hole Mini MLC easily accommodated all of my gear, proving that it's worthy of its name.

About These Bags

So what are the qualities of a hard-working travel backpack? All the bags we chose for this evaluation had to:

  • Accommodate and logically organize everything you’d need to be comfortable/productive/entertained onboard the plane and whatever spillover there might be from your carry-on.
  • Function as the go-to bag when you get to your destination, whether that be day hikes into the mountains or business meetings in a boardroom.
  • Do double duty as a quick overnight bag, fitting a change of clothes and a second pair of sneakers or slippers.
  • Wear comfortably on the back for long stretches of time.
  • Fit (with a bit of creative shoving and squishing) within the roughly 9 x 10 x 17-inch space underneath the typical airline seat. (More on this later.)

In terms of price, the most expensive pack costs $300, while the AmazonBasics crept only slightly above $50. But the mean price of roughly $150 suggests that you don’t have to spend a fortune. Materials, carrying comfort, internal organization, and structure also varied widely among backpacks and did not necessarily correlate to price.  And bigger isn’t necessarily better: Filling the largest pack to capacity could just leave you with a bag that is impossible to straight-jacket under the seat.

The Results: Which Travel Backpack Should You Pick?

While this very much depends on your personal priorities, I think there are a few things most people would agree that they look for in a travel backpack. It should be well organized, with lots of slots for smaller items. A bag that’s one empty maw can leave you constantly frustrated trying to retrieve what you need.

Likewise, it should have enough structure so that it’s not just a sack with shoulder straps; structure helps stabilize the pack, so you’re not using your muscles with every step to prevent the load from squishing around. And it should be fairly burly, with oversized zippers and handles, so you can open and close compartments just by feel and with operational ease. 

All of that pointed me toward one backpack: the Patagonia Black Hole Mini MLC for its winning combination of size, utility, comfort, and sturdiness. Though they didn’t quite measure up to the Patagonia, other standouts were the Incase EO Travel Backpack for the business traveler and the ebags Pro Slim for strong value and right-sized comfort.

The Process: How I Evaluated These Packs

Because these bags are meant to sneak aboard an airliner as your personal item, my editors and I felt it was important to check their “stowability” in a typical underseat area. The thing is, unlike with carry-on bags meant to fit in an overhead compartment, there is no standard measurement for the space under coach airline seats. It varies from airline to airline, as well as from plane to plane within an airline’s fleet.

But we needed something, so we used United’s regulations, which permit a maximum of 9x10x17 inches, and built a plywood box to those dimensions. We also thought it was important to simulate the in-flight experiences of fitting the bags beneath the seats and removing them, propping them in a lap, retrieving contents, and stowing them again. So we also fashioned a wooden facsimile of a seatback using the pitch measurements from this diagram on the FAA website that an FAA spokesperson confirmed is representative of the coach seating configuration on many planes. The rough average is about 30 to 32 inches between seats when measured from the top of one seatback to the top of the next (which is how the airlines measure such things). This can amount to as little as a meager 2 inches or so of kneeroom depending on how long your legs are. 

I’m calling my fledgling carrier Plywood Air. I think the honest tagline “Exactly What You’re Expecting” is very refreshing!

A bulky bag like the Amazon Basics can be a tight squeeze. Packed full, it may need to go overhead.

The way airlines squeeze rows so tightly together means your feet are frequently invading that space meant for luggage—because there’s really no choice. In my evaluations of packs ranging between 15.5 and 21.5 inches in length, only the shortest ones completely fit in the plywood bin, and even so, my shoes still overlapped the box. The FAA spokesperson warned that it’s up to the airlines to enforce egress space that allows passengers to retreat to the aisle, and you’ll see in my reviews mentions of bags that a flight attendant might ask that you stow in the overhead bin instead. 

We also considered comfort. Does the backpack dig into your spine or mold to your body so you barely notice it’s there? These things matter, whether you’re traipsing through airports or using it to stash souvenirs and carry a map, raincoat, and sweater once you’ve arrived. 

To find that out I spent a few weeks carrying these backpacks, plus pedaling them around on an e-bike, sometimes in the rain to see if they did okay with downpours (short answer—yes, mostly) plus playing tourist in my own town of Hudson Valley, New York, by shopping at the greenmarket and using the packs to carry groceries, and strolling the supermarket and the local Lowe’s. How is that any different from being stuck during a 2-hour delay at JFK? For one thing, nobody’s nearly as cranky. Also, nobody’s wrapped your fruit in 15 layers of plastic or wants to charge you $12 for a beer.

Capacity and Functionality

Below you can see the items I typically pack, and also an alternative, a tidier packing list from my wife, an academic who doesn’t have to bring as much as I do on the road. Her contents fit without drama into every pack I evaluated. My contents? Not so much. Literally. The total heft of what I chose to carry tipped the scales at 17.5 pounds. That shocked me, because nothing on my list felt particularly porky. But it all adds up, which is precisely the point of doing this sort of evaluation.

Among our specs we’ve included whether or not a pack includes an external water bottle holder (because that’s just handy), a dedicated spot for glasses, and niceties like a key hook and exterior grab handles, as well as available waist and sternum straps that really help distribute weight.

No bag is perfect; some had extra capacity but were a difficult squeeze, piling out over my shoes. Others were likewise plenty capacious but shimmed into that cubby a little more artfully, typically because they weren’t too wide, just long. And some couldn’t hold everything but slid easily into the underseat storage area. I’ve noted these observations in the reviews. Whether it’s better to have a smaller bag that can’t hold all your stuff but is easy to cram in front of your Converses or take a larger bag that will hold everything but might end up in the overhead is a personal choice every backpack-toting traveler has to make on their own.
