There’s only a few hours left in Amazon’s Prime Day sale, which means the deals are starting to wind down. But if you’re looking to grab a new backpack for your upcoming summer adventures, it’s not too late to score a 20% discount on this Dinictis 40-liter travel backpack. That drops the price down to just $29, but this deal is only available for the blue option.
As a full-time food and travel writer, I’m constantly flying to different places all over the world — in fact, I take at least 50 flights a year. Wherever I go, my highest priority is that I have a spacious carry-on bag that I can easily hoist into the overhead compartment — something that’s also versatile enough to accommodate all my travel essentials.
It doesn’t take a professional traveler to know that having just the right luggage is essential. However, because I fly so often, I’ve tried out just about every type of carry-on bag you can find. And I say this with complete sincerity: This Dinictis backpack is the single best carry-on bag I’ve ever owned.
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 $40 at full retail price and that often goes on sale for less. If you have travel plans coming up this 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 superlow price too.

When only a backpack will do
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 10kg, or 22 pounds, the weight restriction for carry-on baggage for many of the discount airlines. Because 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
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.
