Fantastic purchase
Size: X-Large, Color: Peacockblue
Bought two sets of the large and extra large backpacks in peacock blue for two traveling for an 8 day island vacation out of the country. No problems with size with American Airlines. The storage capacity was fantastic with room to spare for selected purchases to bring back. Color and fabric beautiful. Padded handle and straps comfortable. Well made with functional, easy to access compartments. Combined purchase with vacuum bags which I'm surprised helped greatly, as well as Gorpuire small foldable hand truck dolly which made transport super easy and when folded, easily fit into the front of the Xtra large bag. Unbelieveable value for the price point on all items. Wish I had taken pictures. LOVE this purchase and may not have to check bags in the future. More stars if I could!

Perfect travel bag
Size: Large, Color: Black
I ordered this for work travel and have used it for several months now. It is the perfect bag. The shoulder straps are comfortable. It can fit a lot of clothing and books and my laptop. My only suggestion is that it has the laptop sleeve on the front which makes it tip forward / front heavy. It would be better placed at the back. I have TSA precheck so I don't have to take my laptop out, so I pack it inside at the back rather than using the laptop sleeve at the front. But other than that, the price is great. The color options are great and the size is perfect. It slides nicely over my roller suitcase handle and I've never had an issue on an airplane with fit.

Cute, lightweight and so roomy!
Size: Large, Color: Amourpink, Size: Large, Color: Amourpink
I am honestly so impressed with this backpack! It is the perfect mix of cute, comfy, and practical. The soft blush pink color is beautiful in person and gives it such a clean, stylish look without being flashy. What surprised me most is how spacious it is. It holds SO much more than it looks like it would. I was able to fit all my travel essentials inside with room to spare, and the different compartments make it easy to stay organized. The side pockets are super convenient, and I love that it slides right onto my suitcase handle for traveling. The straps are also really comfortable and padded, so even when the bag is full it still feels easy to carry. The material feels lightweight but durable, which makes it perfect for travel, work, day trips, or even everyday use. If you want a backpack that is both functional and aesthetically pleasing, this one is definitely worth it. Cute, cozy-looking, lightweight, and surprisingly roomy!

Amazing product!! I use it so much
Size: Large, Color: Amourpink, Size: Large, Color: Amourpink
Absolutely LOVE this back pack I use it all the time! It holds a ton of stuff and has a lot of pockets and holds a good amount of stuff. It’s great for a simple sleep over and even flights. It’s very durable and great as a personal item on flights. The strap to keep it on your roller bag is great and it also has a ton of straps to adjust it

Spacious, organized, and perfect for travel!
Size: Large, Color: Black
This travel laptop backpack is absolutely fantastic! It's spacious and well-organized with multiple compartments for everything you need. It's airplane carry-on approved and fits perfectly in the overhead bin. The laptop compartment holds up to a 17" laptop securely with great padding. The water-resistant material keeps everything protected and the straps are comfortable for long trips. Great quality for the price. Highly recommend!
