I am floored by how amazing this carry-on backpack is. You get so much value for the price paid. The design is well thought out. There's a lot to like, from the quality material to the accessories included. I almost can't believe what a bargain this is for the price. Here's my bullet-point list.PROS:+Comes with 3-digit combination luggage lock+USB input allows you to connect your power bank on the inside and connect your cable on the outside for easy access+Outer material is water-resistant+Outer lining feels durable and "thick" but not too heavy+Accessories galore: Shoe bag, large cube, water resistant cub, medium cube+Shoulder straps can be hidden inside the pack or used as a backpack+Interior design has multiple compartments and zippers for organized storage+Squarish size of the backpack offers maximum capacity+Bag handle can be used like a carry-on+Luggage belt can be used to carry this on top of luggage+Two tone color scheme (most designs) is attractive+Padded sleeve inside is suitable for laptop+Side pocket can store water bottle for quick accessCONS:-If you remove the backpack straps from their zippered pouch, there's no way to zip up the pouch to prevent water from getting in

Perfect for an all carry-on trip on American! I don’t love the laptop pocket in the front because it limits the use of the wet pouch, but it holds quite a bit and fits under the seat. Had to take the water bottle out for the aisle seat and it didn’t fit on the regional jet with only one seat, but fit just fine in other seats. No more getting stuck on the bottom of the seat either. Overall, a great bag that holds a good amount and looks professional. I do wish it had 2 bottle holders and the laptop pocket in the back, though.

Used this bag as my carry on for Cancun Mexico and it held it's own and fit comfortably on the plane, under the seat in front of me and the overhead storage. Very nice design . Love hideaway pockets and compartments for easy access to my passport.

OK, to be fair, I have not traveled with this yet, but having received this I am even more excited about my upcoming trip. I may actually get away with just taking this and leaving my suitcase behind. I do not have a laptop, so can use that space for some items. I like the expansion zipper, and the clasps on the size that will help me cinch in the bag. I might even be able to fit this under a seat which is a plus because I get really frazzled when there is no room in the storage area directly above my seat. It has a slot in the back for concealed pocket area, which zips, and is a perfect place for passports or wallet. It also comes with two packing bags and a shoe bag. It came with a lock, but I have zero idea what the combination is or how to lock it, but the combination was 000, so thankfully I was able to get it off the bag. This was not a big deal for me, but still, a piece of paper with a combination would have been nice to have.I have been searching for a bag that had the following:1) expansion capability and cinch straps to tighten the depth.2) water resistant3) durable fabric4) water bottle pocket (not sure how well bottle will stay in, but there is one there5) concealable shoulder straps (because sometimes I prefer to carry with a handle and those straps are a nuisance and a trip hazard)6) USB function - you need your own power-pack and cord, but there is an inside pocket for the charger. The cord that goes to the power pack was not already inside the bag, and we had to figure out how to get that in securely, not sure if that is standard or not.7) lightweight - this is as light as I can get with all these featuresZiippers seem to be durable, and overall I think it is going to function exactly as I had hoped.

I am an avid traveler, and I have never had a backpack as functional, versatile, durable, and nice looking as this one! The storage capacity, zippers, safety features, pockets, etc. like this one. It literally fits everything! There is space for a laptop, water bottle, inside pockets for security, and more. Then it came with extra bags, too, and if you haven’t traveled with luggage bags for your items you are missing out! This is a MUST BUY!

I used it for a weeklong trip and managed to fit everything I needed: outfits, toiletries, and even my camera gear. The included four packing cubes are a lifesaver. Each cube has a specific purpose—clothes, shoes, and toiletries—and kept my belongings neat and accessible throughout the trip. It fits perfectly as a carry-on under the seat or in the overhead bin, saving me from baggage check fees. The padded, breathable straps and adjustable chest strap made it comfortable to carry, even during long walks through airports. The luggage strap was a thoughtful addition, making it easy to secure the bag on my suitcase handle. Plus, the anti-theft back pocket is great for peace of mind when storing valuables like passports or wallets. The built-in USB port is a standout feature. It’s super convenient for charging my phone while walking or waiting at the gate. The water-resistant polyester material and sturdy zippers held up great during light rain, and the reinforced stitching gives me confidence it’ll last for years. This expandable travel backpack ticks all the boxes: spacious, organized, durable, and comfortable. Whether you’re a weekend traveler or heading out for a weeklong adventure, this bag delivers exceptional value. Highly recommend!
