I found it very nice looking, well finished and love the possibility of being slim for daily commute as well as expandable if need to carry more stuff. Quality also looks nice, will see how long it will last, but I am very satisfied by now.

This is a perfect bag for travel. Fully-expanded, it is the exact maximum size allowed for a personal item (under-sest-size bag) on most major airlines. It has numerous pockets, allowing for easy access to different types of items (tablet, chargers, papers, snacks, travel pillow, etc.). The hidden passport pocket was also well thought out. It also has a strap to attach it to the wheeling handle of a rolling suitcase. Over all, it was a perfect companion backpack to a full-size carry-on bag.

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.

I love this backpack. It holds shape well and fits my laptop as well as my iPad and other items. It is expandable and looks great!

I cannot walk through the airport without getting a compliment on this bag. But beyond the compliments, it has the compartments to do everything that I need and even expands when I need to pack clothes or an extra pair of shoes to accompany my carry-on. Go ahead and get it right now.

Robusto e capiente con una buona linea

Just thanks!

Returned, not versatile enough

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.

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.
