I ordered the black bag. The exterior of the bag looks very nice. It has a nice modern and slim look. Its also a really good size for everyday use or travel (as a personal item). The interior of the bag lacks - as it is made of a shiny polyester material that is in an odd brownish color. It looks as if it wasnt thought out and they just used whatever color material that was around when making it. I have no idea why they didnt use a nice black or gray color interior color. The material on the inside does not look very durable either... Also, there are wires in the bag for charging. However, since they use thin cheap wires, it will not work for fast charging. Also, they use the old micro USB instead of USB type-C. So while its a nice thought, theres clearly improvements needed there. Overall, Im really happy with the exterior of the bag and the bag does what I needed for. So Im okay with the flaws. Note: I tried uploading pictures, but keep getting an error message. If they fix this, I will add pictures if possible.

I have been using this product last 3 months and it is great. It fits my 15 inch Macbook pro, small keyboard, trackpad, a couple of books easily without using extension part. I highly recommend this product.

Love that bag, 15’ laptop fits perfectly, very comfy

I used it to travel to a work event and this backpack has met my expectations. It has 4 different sized compartments. I was able to fit my IPad, 15in. laptop and chargers, mouse, etc. and still had a lot of room left to add more stuff. The fabric is not cloth, it’s more like a vinyl fabric which I like. I highly recommend this backpack.

Not bad, but not perfect: Bag gets a bit too floppy when completely expanded. Zipper to switch to compact mode blocks access to water bottle holder. Would be nice to have straps to cinch down the bag when in expanded mode. Used it for a month of traveling. Problems noted stem from actual experience.

Great. Stylish. Simple yet complex features. Would highly recommend.

Exactly what I hoped for. The perfect laptop backpack with chest stabilizer buckle. It looks compact and quality, and then if you need more room, it expands nicely. I like the look - combo of faux leather and backpack material makes it look expensive. Zippers and zipper pulls seem quality. I also like the top handle for grabbing. Very comfortable on even when filled to capacity.

It’s very comfortable and sleek. The chest strap helps take the weight off my shoulders.

This backpack is as close to perfection as possible. Its not the cheapest, but its worth the price. It is not the type of backpack you want if you need to carry tons of heavy stuff. It is the backpack for traveling light and comfortable and it is fantastic in that role. It works equally well in compact mode and when it is expanded. Excellent quality, good amount of compartments, water proof, well designed. Things to notice: it is not as heavy as some reviews suggest. I was worried about it a little but, but it turns out the empty backpack weights 1.1 kg, just as it says in the description. The laptop compartment has nice strips, but they are useless if you have a small ultrabook. So my 13 inch Dell is too small to be even close to those strips. As I plan to use the backpack on a long trip with my motorcycle, I was worried about the strength of the strips. Im still not sure how strong they are, but at close inspection they seem more than adequate. Time will tell, but I see not reason to be worried. General quality of all parts of the backpack is admirable, definitely more than average. The USB plug is useful, but you should know it is accessible only in extended mode. I really like a side pocket. You can reach it quickly, with only your right hand out of the strip. Also, there is a compartment opened from the back for more precious thigs. It is an excellent idea and works very well. It is quite comfortable to carry. I wasnt sure about it, because the backpack looks square. Human body is not a robots body, so square things are not always a good idea. But in this case it works well for some reason, probably due to the size of the backpack. It is more comfortable than it looks. And the strips are easy to adjust to keep it as high or as low as you need. All in all, very good design. Heres one more thing I love: the backpack does not have any stupid logos anywhere. Three cheers for Zinz here. Heres my philosophy: if a company wants me to be their walking advertisement they should pay me, not the other way around. In this case Zinz opted for a of humble decency and removed all logos. Im quite happy to pay more for things with no logos. The backpack looks good. It looks clean, pleasant and modern. Black colour is perfect choice in this case. Ive had more backpacks in my life that I can count and used them for everything: summer trips, winter trips, commuting, bicycles, motorcycles, mountains, trains, 1 day trips, 3 month trips, you name it. This one is the best. By far. Unless of course you need something really big on your back. But remember: this is not a camel-and-horse-sort of backpack. This is its-always-with-you-sort of backpack. Consider it an extension to your pockets.

I was looking for a slim backpack that had a lot of pockets for carrying all my accessories. This backpack fit the requirements but when I received it, I was surprised to find the inside to be brown instead of the gray that was shown in the pictures. Not sure if Im gonna keep since I dont care for the color of the interior.
