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!

Good bag for a good price
Size: Large, Color: Amourpink
Really loved this backpack. I got it after reading all the reviews and wanting something for travel. The inside pockets with extra compartments that are water proof or organizing was a really nice touch. I traveled on airlines with this a few times and then started using it for school as well. It help up really well. I tend to be kind of rough on things and unfortunately the zipper broke. I'm unsure of if I over stuffed it or it was just a cheaper zipper. I would have considered resorting it because I used and loved it so much but my mom's dog got to it and it was not salvageable after that. I would recommend this specifically as a great travel backpack for the air port but it can easily double as an over night bag or school back pack.

So big, but lightweight!
Size: Large, Color: Amourpink
I bought this backpack to have as my "personal item" on the many flights I have to take. It is the perfect weight, having a place for just about anything you'd want to have during a flight, as well as having your carry-on items. The charging port is a bit of a challenge to plug in because of how you have to position the cord, but it is doable. I did not end up using the charging feature on my most recent flight, but I can see how it would be helpful for the travel that does not provide many charging stations. I have some serious back issues, but even full, I found this backpack to be a reasonable weight. I cannot attest to it's durability at this time, as I've only taken it on two trips now, but it is a great bag. There are many compartments, which can be good and bad. I recently put my wallet with all my identification and cards in a compartment that was easily missed. I thought I had lost my wallet and was panicked about how I'd get on my return flight if I didn't find it. After completely emptying the bag in my friend's car, and running my hands all over the compartments, I found the wallet. Here's the thing, my wallet is not little, so you can see that the walls of this backpack are pretty thick. The pink color is more of a dusty pink, which I find to be more attractive than a bright pink for something like this.
