My Laptop Would Have Been Stolen at That Market. The MATEIN Backpack Stopped It.

I have been traveling carry-on only for eleven years. In that time I have walked through the Grand Bazaar in Istanbul, elbowed my way through Chatuchak Market in Bangkok, and navigated the medina in Marrakech with a full pack. I thought I had seen every pickpocket trick there was. Then, on a Tuesday afternoon last October, someone proved me wrong, and a $29 backpack is the reason I am still writing this on my own laptop.

I had switched to the MATEIN 17-inch anti-theft travel backpack four months before that trip. Not because of some grand plan. The main reason was practical: my previous bag had two external pockets on the sides, and I had started wearing it on my front through busy transit hubs because I was nervous. It looked ridiculous. I needed a bag whose security was built into the design, not something I had to compensate for with awkward posture.

The MATEIN solved that immediately. The main zipper opens against your back, not outward. When you are wearing the bag, the zipper pull faces your spine. Someone would need to ask you to step aside, remove the bag, and flip it around before they could even attempt to open the main compartment. That is not how pickpockets work. They need five seconds and a crowd.

In Marrakech I was in the Jemaa el-Fna square, the big open plaza that turns into a full sensory event around sunset. I was watching the food stalls set up when I felt a hand, low on my back, near the base of the bag. Not grabbing. Just probing. Looking for a zipper pull. I spun around and saw a teenager already moving away, unhurried, already looking somewhere else. He had not found a handle to grip. There was nothing there.

He had not found a handle to grip. There was nothing there. The hidden back zipper had done its job before I even noticed the attempt.

I want to be honest with you about what the anti-theft design does and does not do. The bag is not a safe. If someone snatches it off your shoulders and runs, it is gone. The security features are specifically about preventing covert access while the bag is on your body, in a crowd, or set down next to you at a cafe. For that scenario, the design is genuinely well thought-out.

There is also a dedicated USB charging port on the outer left panel. You run a short cable from your power bank inside the bag to a port on the outside, so you can charge your phone without ever opening the bag. In a market, at a train station, or sitting in a departure lounge where outlets are scarce, that small detail is worth more than it sounds. I charge during boarding and arrive with a full phone.

The laptop compartment fits a 17-inch machine, which matters more than most people realize. I carry a 15-inch MacBook Pro and it fits with room to spare. The padded sleeve holds the laptop vertical against your back, which is the safest orientation during transit. When I hit TSA, the dedicated laptop slot opens flat, lays the laptop on the belt in one motion, and closes the same way. No digging, no shuffling, no holding up the line.

I have used this bag in airports on four continents now. The zippers have not split. The straps have not frayed. The back panel ventilation keeps it from being a sweat trap on warm travel days, though I will be straight with you: it is not a Osprey in terms of shoulder ergonomics. If you are hiking eight hours with a full load, it will remind you that it is not built for that. For urban travel, transit hubs, and day excursions from a base hotel, it is excellent.

The bag also fits under most airline seats, which is my single non-negotiable for a personal item. I have tested it on Spirit, Ryanair, and ANA. It slides under every time with a few inches to spare. That matters when the overhead bins fill up at boarding group four and a flight attendant is eyeing carry-ons.

What I Would Tell You If We Were Sitting at My Kitchen Table

Here is the honest version: the MATEIN is not a premium bag and it is not trying to be. The material is durable polyester, not ballistic nylon. The price reflects that. What it is, is a bag that thought carefully about the specific problem of traveling through crowds with a laptop, and solved that problem at a price that does not require you to think twice about it.

If you are a carry-on-only traveler who moves through cities and transit hubs with a laptop, and you want the peace of mind of knowing a stranger cannot quietly open your bag from behind, this is the straightforward answer. You do not need to spend $200 to get that protection. The MATEIN anti-theft design works because of how the zippers are positioned, not because of some expensive material. That is a smart engineering choice.

I still wear it. I wore it on a trip through three countries last month. The laptop came home fine. So did I.
