How many backpacks do you know that is TSA friendly like this one? My travel backpack holds everything I need while on the go. With a firm handle and soft straps I never get tired from holding it. I love how there’s a pocket just for my laptop that keeps it secure and safe. I never have to worry about my laptop being in my backpack when it rains due to the waterproof, lightweight material the bag is made out of. It even has a charging port so I’m able to charge any device that uses a USB port. By far the best travel bag I’ve ever had.Love it! Very sturdy. The only thing I would recommend is to have a hole where you could run your wire through to the back compartment.My kids will be using it for school and they love the bags. They are getting older now and the extra space and the laptop storage comes in very handy. Love the design and the build. Recommended to everyone that is looking for a good backpack at a great price.For air travel, I use a rollaboard as my luggage and a backpack as my "personal item." My only requirements for the backpack are that it has a luggage strap, something to secure it to the extended handle of my rollaboard, and it qualifies as a personal item.My wife claimed the laptop backpack I was using for years for a business trip, and I needed something inexpensive to use for when I flew out to join her. This backpack fits the bill well enough.It has the trolley strap, so we're good to go there. Unfortunately, it's 19" long, and that's 2" too long to meet airline requirements. I don't think anyone will be making a fuss, and still think it's worth mentioning.Otherwise, this is a usable, no-nonsense backpack with a few nice features that I didn't notice in the listing. For example, I like the detachable keyring, not so much for keys, but it lets me secure a small bag and lets me get at it easily instead of digging through the bottom.There's a USB cable that lets you connect to a battery (not supplied with the backpack) and provides a USB socket on the outside for easier charging of my devices. It would have been even nicer if there was a pocket provided to hold the battery instead of letting it bounce around inside the bag. Another USB-related annoyance is the exterior USB connector. It's misaligned, making it a struggle each time I want to plug in a cable.Otherwise, the material is thin and has a mild industrial smell that's common with things imported items that use synthetic materials these days. Everything else is the "least possible" to provide a backpack that will last, if not for a lifetime, at least past the allowable return window.So, what does all this mean? Well, if your requirements are the same as mine, to have an inexpensive sack to hold stuff with a trolley strap, and don't plan on using it frequently, then this should be fine. However, if you want a backpack that you'll frequently be using, then perhaps seek out something that costs and provides a bit more.Bought this for my husband who recently went back to school. He carries a binder, laptop, charger, and textbooks in this backpack with no issues. Has enough pockets to keep everything organized and zippers are easy to open and close. The all black looks professional enough to use for work stuff as well. It is a good size for adults (husband is 5'11") so would probably be a bit large for small middle schoolers or elementary students.Works great! Larger than expected when it first arrived but worked out nicely. Holds everything I need it too for school, including my laptop and multiple books. Straps are nice and padded and don't bother my shoulders. Opens easily for air travel which is a huge plus! Very nice in the rain, keeps everything inside nice and dry.This bag is perfect for middle-school to adults who use laptops. Very stylish. Great deal for the price. Laptop fits perfectly inside! A great buy!
