Quality
Color: Upgrade-apricot, Size: 16 Inch
Am not disappointed buying this bag it’s spacious all different type of pockets the zippers are so unique the thickness is everything to talk about . I used this for my work bag that I carry 5 days of the week with my uniform,shoes,water bottle,phone,tablet etc and it’s still leaves a lot more space the firmness and sturdiness is 100% ..So comfortable the padding on the back and the shoulder keeps you relaxed. This is value for your money , my coworker are so inlove with my backpack

Very functional and spacious!
Color: Upgrade-apricot, Size: 16 Inch
I wasn’t expecting to love this backpack as much as I do, but wow —it’s everything I wanted and more. The apricot color is soft and pretty without being too “girly,” and the fabric has a nice matte texture that feels durable yet lightweight. It doesn’t have a plasticky smell at all, just a clean, new bag scent right out of the packaging. The compartments are super well thought out. I can fit my 16-inch laptop, chargers, skincare pouch, and even a change of clothes without the bag looking bulky. The back padding is surprisingly comfy, especially during long airport days, and the straps don’t dig into my shoulders. It sits well on my carry-on handle, making it the perfect travel companion. If you’re into functionality and aesthetics, this is it.
