Decent basic backpack
Color: Green
This is a good, basic backpack. It doesn't have a lot of bells and whistles, but it's a solid choice. The sizing is average, it will hold several books and notebooks. The padding felt adequate for most items, but I'm not sure how much I would trust it with an expensive Mac book. The straps were easy to adjust and padded enough. I appreciate that it could be folded up and put into another bag if you needed an extra bag while traveling - it would make a good day pack. Overall a good deal for what it is.

Sturdy, attractive, comfortable, large capacity; lightweight, back strap to fit luggage
Color: Green, Color: Green
There are several good features for this BAGOK Lightweight Nylon Backpack, starting with the attractive green color that I chose. It is light weight and foldable yet has lots of pockets. The stitching is good, and the zippers work nicely. The back adjustable straps have padding and netting for cooling. There is also a handle on top for carrying and a backstrap to fit over luggage. On the front, there are two zippered compartments. The small one at the top could hold a wallet or passport or tickets. The larger front pocket is roomy with the zipper under an overhanging fabric. Inside is lined with black nylon. The frontmost large compartment extends the length and width of the backpack. The larger main compartment is at the back and has padding to safely store a laptop, e reader or other electronics. There are two nylon pockets inside the main compartment on one side.
There are two outer side pockets. I was able to fit a water bottle in them when the inside was empty. However, if the entire backpack is filled, I don't think a water bottle will fit. One drawback is the side pockets are not elasticized--they don't stretch. I will use this for day trips and travel. It is too large to be a personal item on airlines, but it could be a carryon. You can get a lot of things in it. The nylon material is sturdy and should stand up to wear. I am short, 5'2" female and I could adjust the straps to be comfortable for me. And it does fold up for storage between uses. This could also withstand daily use for hiking, work or school

Finally found the perfect backpack!
Color: Apricot, Size: 17.3 Inch
I’ve been searching for a backpack that could fit my 16-inch laptop and my other uni stuff since i commute, without looking huge on me, I’m a small girl, so most big backpacks just look bulky and awkward. I wanted something slim and sleek, not one of those backpacks that stick out and have that “belly” shape.
After a lot of searching, I finally found this one, and I absolutely love it! The material feels really high quality, and the design is just perfect. I got the 17-inch size, and it fits my 16-inch laptop comfortably.
There are so many pockets for organization, plus a separate padded compartment just for the laptop, which I really appreciate. It also has a handle that easily slides over my suitcase handle, which is so convenient for traveling (I travel a lot, so this feature was a must).
It’s comfortable to wear, the straps are adjustable, there are bottle holders on both sides, and overall it just looks clean and stylish. i got the beige color one. which i love.
I’m really happy with this purchase it has everything I was looking for. I’ll attach a short video showing all the pockets and features because it honestly deserves it!

Perfect and not bulky
Color: Apricot, Size: 17.3 Inch
Love this slim backpack, plenty of room for my laptop and so much more. Lots of zipper and mesh pockets. I like the separate compartments for the laptop. It’s well designed and very functional. I wanted something that was not bulky and this fit the bill, it’s really great. The material is nice and easy to keep clean. Seems well made, I’ll update down the road if that changes. I recommend this backpack.

Perfect work travel bag!
Color: Black, Size: 14 Inch
Perfect work bag! I was looking for something for a petite frame. Can fit a lot in it, worth the money, love all of the pockets. Can carry two ways - either with handles or wear on back like a backpack
