ZINZ Slim and Expandable 15 15.6 16 Inch Laptop Backpack Anti Theft Business Travel Notebook Bag with USB, Multipurpose Large Capacity Daypack for Men & Women, Blue

Good quality. Very versatile.

Very light. Slim profile. Easy to expand. Quality materials. Ergonomic straps.

Nicely made, very good fit, the expandability works well (not obvious/in the way when collapsed, spacious when open).

Wir haben viele Ausflüge gemacht mit dem Rucksack und da ist er immer sehr gut

I love this bag. I bought it 2 years ago and I have no regret.

Lets not waste time, the let down is the laptop position which results in 2 issues, one is weight balance and the other is deformation. Now I will explain the significance, but with enough information for you to assess your situation. My laptop weights approx 2kg, it isnt light and that will exacerbate the issue. When the bag is fully compressed (i.e. not expanded), everything works a treat because the laptop sits right next to your back when you carry it. When the bag is fully expanded, the laptop sits in the section furthest away from your back which will be up to 10cm. It is a really weird feeling and you realise how important it is that the laptop is against your back when you carry it. The sciency reason is that we find things easier to carry when the centre of gravity of those things are closer to our bodys centre of gravity. Think about carrying a 5kg sack, or a baby, against your chest vs holding it out in front of you. Back to the backpack, I find myself having to lean forwards more which cant be ideal for posture, and there is a persistent feeling of someone pulling your backpack given the position of the laptop. It is weird. There are 2 subsets of issues with the expanding bit too, Ill touch on both because this really doesnt work well... The first is the non-ideal scenario where you expand the backpack to carry a couple of small items that dont completely fill out the space. The issue is the laptop itself is so heavy that it compresses and deformed the expanded area if there is space in there, which results in the backpack drooping. The second, is the ideal scenario where you fully fill the expanded area and dont suffer the deformation but still have the weight of the laptop feeling like its trying to pull you backwards. I really cant fault the quality or anything else about this backpack, but the 1 thing I do fault is very significant and I regret buying it. It will serve me for the time being in its non-expanded state, but if you want to make use of the expansion and have a heavy laptop, seriously look for a backpack where the laptop will always be sat right next to your back.

I will be taking my laptop when I travel in July and this bag is amazing. Its roomy, sturdy, and the perfect size. Plenty of room for not only my laptop but also extra clothes, camera gear, and incidentals. Highly recommend this bag.

Materiali di ottima qualità, ottimo rapporto qualità prezzo, versatilità. È come avere due zaini in uno! Lo consiglio

This bag served its purpose on a 7 day Alaska cruise. I didn’t want to haul my North Face backpack so instead I went for this bag and I couldn’t have been happier. You get a lot of storage for the size of the bag. It repels water just fine.

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.
