Being a food and travel writer means I'm constantly flying to different places -- I fly at least 50 times a year. No matter where I go, it's important to me to have a carry-on bag that's versatile and designed for maximum packing efficiency. I also value having a bag that I can easily hoist into the overhead compartment if need be. It doesn't take a professional traveler to know that having just the right carry-on is essential.
Since I fly so often, I've tried out just about every type of carry-on bag you can find. And I say this with as much conviction as I can muster: This $30 Dinictis backpack is the single best travel accessory I've ever owned. And even though Amazon's Big Spring Sale has officially ended, it's still discounted between 10% and 17% off (depending on which color you choose).
I'll admit that other carry-on bags might look more stylish and come in a wider array of colors. But I have yet to find one that meets my needs for durability, efficiency and affordability better than this well-designed travel bag that's just $30 for the dark gray version. If you've got travel plans coming up this spring or summer, this is the carry-on you want to bring along, full stop. And don't worry about misplacing your backpack. Simply throw in an AirTag, especially when you can get a pack of them for a super low price right now.

When only a backpack will do
It's available in four colors: gray, dark gray, blue and black.
To be clear, my backpacking days were over before they started. Without the means for serious travel before age 25, my life as a traveler didn't kick off in earnest until I was equipped solely with roller-bag sensibilities. As an [age redacted]-year-old, when I scheduled myself for a bus trip along the coast of Peru, with overnight stays in modest accommodations, suddenly a roller bag felt kind of… well, prissy. Roller bags are decidedly inconvenient when it comes to unpaved or nontiled surfaces; plus, it's just not a good look when the vibe is more low-brow than luxury. This wasn't a backpacking trip by any means, but a backpack was definitely called for. One that could accommodate a week's worth of clothing, amenities and a laptop but still potentially fit in a locker.
The Dinictis 40L Travel Backpack came into my life for this particular trip, exceeding my expectations. Since that Peruvian adventure, this bag has come with me on every single trip, no matter the occasion.
A backpack that works like a suitcase
It's a backpack that packs like a suitcase.
Many travel backpacks are spacious and compartmentalized, but the Dinictis 40L Travel Backpack operates like a suitcase. It opens along three sides, so you can flip it open like a suitcase and pack accordingly, with straps for holding your clothing in place. This makes finding what you need much easier than shoving your belongings from the top down like a typical backpack. A side handle even allows you to carry it like a suitcase.
When full, it can easily hold up to 10 kg, or 22 pounds, the weight restriction for carry-on baggage for many of the discount airlines. Since it's a backpack, nobody has ever asked to weigh it for compliance. It will always look lighter than it is.
Store your laptop with confidence
As a writer, I always travel with a laptop, so I'm concerned with its portability as well as safety. That said, I hate having it pressed right up against my back, which can be stiff and, depending on where you're going, sweaty. The laptop sleeve on this model is ideally situated near the (sweat-free) front of the pack but isn't the most outward-facing compartment. Honestly, protected by a foam divider, the laptop feels hidden, even when packed to the gills.
Outside pockets are a must
A side handle is key for navigating public transportation.
I am team-soft-body, even when it comes to roller-bags, for two reasons. First, it's much easier to shove last-minute items into an already zipped suitcase without the clamshell action of a hard case, and second: outside pockets. Who can travel without these? (No, I really want to know…) This backpack has two outer pocket compartments for miscellany, arguably three when considering the extra space in front of the laptop sleeve -- and four if you include the handy water bottle holder. There are even compartments within the compartments. These are the sorts of details that separate the high-functioning from the holding-up-the-line travelers, in my opinion.

A personal item that can masquerade as checked luggage
Safe laptop storage is crucial for a travel writer and this bag has a dedicated sleeve.
Many travel backpacks have an infrastructure that keeps them in a certain shape, even when empty. The Dinictis model has enough structure to keep its sides afloat while you pack it, but its essence is still as a lightweight, fabric backpack. If you've ever been asked to prove that your carry-on actually qualifies as carry-on, you will understand that "smushability" is an important factor. I have packed this backpack for a weekend away and brought it on board as a personal item. (I will fly Spirit Airlines, but I will only do it while giving them as little of my money as possible.) It can totally fit under the seat in front of you when necessary.
The beauty of this travel backpack is that it is also suitable as checked baggage, with heavy-duty fabric that can withstand the journey. The straps can be unclipped and tucked away, and the body cinched by additional clips, for a tidy package that doesn't make you feel panicky when you watch it being whisked away on the baggage conveyor.
I've had many trips where it leaves with me as carry-on, and returns as checked luggage. Even in the lighter gray color, its durable material doesn't reveal that it has ever seen the tread of a baggage carousel. It was the function I didn't even know I needed, but now I never travel without it for this purpose.
