MATEINMATEIN Carry on Backpack, Extra Large Travel Backpack Expandable Airplane Approved Weekender Bag for Men and Women, Water Resistant Lightweight Daypack for Flight 40L, BlackOEKO-TEX STANDARD 100

i studied abroad in 10 countries (semester at sea) and only used this backpack to go in each country. it stayed in perfect condition for the 4 months i was used it. I'm a chronic overpacker and this actually kept up quite well for that. You can use the straps that buckle together to buckle water bottles, external bags, etc. I also love that there is a pocket right where it is flat on your back so i wasnt worried about anyone opening a zipper and stealing my computer. i was honestly scared to buy this cause i dont trust amazon's quality sorry but im so happy i got this cheaper alternative. if you are stuffing it full like i was it won't fit under an airplane seat, but it fits well in the overhead bins. I genuinely put this backpack through the ringer and it never failed me. I see some comments about zippers and I had no issues.

One of the best purchases I've made. For it's size it easily held 3 days worth of clothes and I'm certain I could've gotten a day or two more in there. I couldn't get my toiletry bag in there but the mesh pocket easily held everything I would've put in it making it unnecessary. The outer pocket held my laptop, it's cord and tablet. It fits carry on guidelines and functions as a backpack to carry through the airport. As there are no rolling wheels you either have use it as a backpack or the handle to carry it like a suitcase, which I guess could be provided as a downside but I knew what I was purchasing so it was fine. All in all a great bag.

The MATEIN Men's Travel Backpack is a perfect blend of practicality and comfort. Its 27L capacity is just right for short trips or daily commutes, and the expandable design offers extra space when needed. The material feels durable and water-resistant, making it great for both travel and outdoor use. I love the lightweight feel—it doesn’t add unnecessary bulk even when fully packed. The multiple compartments keep everything organized, from electronics to clothes and smaller essentials. It also fits easily under airplane seats, making it a great carry-on option. Stylish, functional, and affordable—this backpack checks all the boxes.

Would like to love this product but the stitching securing the bottom half of one of the shoulder straps to the bag came completely unraveled after a couple of uses.Edit: The company reached out and offered a full refund, but I asked for a replacement instead because I really liked it on my two trips, which they mailed without hesitation.I was looking for a carryon without wheels because I was taking a train to the airport for my first trip, and this bag falls within those dimensions and is large enough to hold several days worth of clothing. I used packing cubes in the main compartment for a 5 day domestic trip and had room to spare. The front compartment easily held my Kindle, noise cancelling headphones and various other personal items, and is spacious enough to accommodate a large laptop. The straps are easy to adjust and it felt comfortable on my shoulders. It made traversing NJ Transit stations and the airport easier than wheeling a carryon around.I am looking forward to working my replacement through it's paces on an international trip later this summer.

I concur with Paul’s review below. My use for a backpack travel bag is so I can be hands-free when making my way through transportation terminals, fumbling for tickets, or reaching for handrails. Also, in some countries there are lots of stairs in terminals (particularly subways) and dragging a roller bag up and down them is hardly fun. It should be obvious that someone planning long hikes or carrying lots of specialized equipment should probably use an internal frame backpack. I don’t expect to walk more than a mile or two at any one time with a bag like this. My travel is rather conventional tourism, and having visited all 50 states and 17 countries on four continents I’ve had a chance to work out a minimalist system that can keep me going through any weather, wet or dry, from about 40°F to over 100°F, and for an indefinite period of time. I do not take a laptop, but an iPod or iPad. Everything fits into this Matein bag and a lumbar pack from Mountainsmith.I’ve previously used a book bag as a travel backpack, but being a top loading bag, digging down into it to get what I need is an inconvenience. When constantly on the move, unpacking for one or two nights is a chore, so a bag like the Matein that opens out like a suitcase is a much more practical choice.I bought this bag along with an eBags Mother Lode as both seemed to be good and I couldn’t decide just from the online info. Both look to be well made, but I kept the Matein and returned the eBags Mother Lode.The eBags Mother Lode has more padding in the shoulder straps but no padding on the back. The padding on the Matein straps is thinner than the eBag but adequate, and it’s nice to have some padding at your back so you don’t get completely poked if you don’t pack right. The eBags Mother Lode came with a shoulder strap and a waist belt, neither of which I need.The overall fit and finish of this bag is quite nice. All of the walls are padded. The zippers look to be rugged and of good quality. I did not have any problems with snagging when running the zippers around the corners of the bag.There is a strap on the back of the bag to secure it to the handle of a roller bag. The shoulder straps are stowed inside a large pocket that could be used for a laptop; there is no separate laptop compartment. The straps attach at the bottom of the bag with metal clips and rings that are easy to operate, in contrast to the plastic ones on the eBags Mother Lode unit, which I found a little hard to disengage. The Matein straps look to be well attached at the top and the bottom rings are sewn into reinforced triangle-shaped flaps that look like they will take quite a bit of stress.The hand straps at the top and side of the bag aren’t as well padded as the eBags Mother Lode, but considering that this is supposed to be a backpack, I don’t have any issue with this; they’ll serve just fine.The product description says there are Velcro compression straps inside the main compartment. This is incorrect (The description may have been corrected by the time you read this.). The retainer system consists of four elastic bands that connect in the middle with a clip. This is the only weakness I found in the bag, and was a disappointment to me, and why my rating is four stars instead of five, as the elastic doesn’t seem much stronger than that in my Jockey shorts, and doesn’t look like it will last all that long. But in the event that the elastic fails, the external compression straps will more than likely suffice. By the way, compression straps are important. I once took a trip with a large backpack bag that had none and the bag sagged like a plastic trash bag and the contents sloshed around uncontrollably.The secondary compartment of the Matein has two zippered inner pockets and a couple of smaller ones that would be handy for pens and such. There is a smaller compartment on the back (the angled zipper in the photos) that measures about 9 x 11 inches which would be a good spot for the small liquids and other stuff you’ll have to remove at security screenings.The construction of the bag looks good. All the seams are straight; exposed seams are covered with binding, and I found only one loose thread. The bag came packed in a drawstring bag that I think I’ll take along as a laundry bag. Empty, the Matein bag weighs about 2 1/2 pounds vs. almost 4 for the eBags Mother Lode, although the eBags Mother Lode is slightly larger and has more pockets. (One of the reasons I returned the eBags Mother Lode is that I don’t like lots of pockets.)This Matein bag is about half the price of the eBags Mother Lode and I am so far quite happy with what I see. When compared to the eBags Mother Lode and another nameless bag I saw in a local department store, this is a good deal. I’ll be traveling with it for about six weeks this summer and if I have anything to add to this when I return, I’ll update then.__________Update:Here’s a follow-up report. I took the backpack on one domestic trip for a week and an international trip for a month. On this latter trip we moved every two nights, and the trip took us through three countries, four airports, numerous busses, boats, trains, taxis, subways, the legendary Heathrow Terminal 5, and the ultimate travel survival test, the London underground during afternoon rush. The pack survived well. I remain disappointed with the flabby elastic retention straps on the inside, but the exterior ones took over and kept things under control. I’m a minimalist traveler — the pack was roomy enough for all my stuff excepting a few things I carry in a small waist pack. The pack came with a thin bag I used for laundry; and it folds in half easily to be stored in its original box. I have no problem recommending this for anyone needing a carry-on pack and I look forward to using it on future trips

This item works very well as a carry on. Although it is a backpack, the inside looks and works like a piece of luggage. I was able to pack a lot of items it is of high quality, expandable, and very durable. This will now be my carry on of choice. It is the perfect size to place in the overhead bin or under the plane seat.

I purchased this bag to fly to Malaysia with layovers in Korea. I liked the option to carry it as a suitcase or use the backpack option. The zippers and seams held up very well. I missed having an exterior pocket to hold my cell or battery backup that would be quick to access. It fit well in the overhead and under seats. i liked the expansion option. Good quality for a good price.
