The backpack is excellent; my 17-inch laptop fits comfortably. I chose this backpack specifically for it; I checked everything on AliExpress. There is an expandable compartment for inspection, I put a pillow in there and it fit. There is also a compartment for some snacks on the go, about 2.5-3 cm deep, and additional compartments on the front of the backpack. On the back, there is a hidden pocket for a phone or documents. Overall, the backpack is decent and the price is good, I recommend it.

37-liter maximum capacity backpack, brand Bange

At first glance, the first impression is that the material is very well-made and "waterproof" (that is, it can withstand a drizzle, but I wouldn't risk using it in a real rain), and the zippers are of high quality. The backpack has numerous compartments, including a compartment for a power bank and charging your phone (great for travel).

As you can see in the photos, the finish is very well done, and it's expandable. It has a specific lined pocket for wet items, which is great for used clothes, for example, or something damp (obviously to be removed quickly).

Backpack as described, great quality, many pockets, arrived on time.

Very beautiful and huge when using the expansion option. Simply a wonderful experience.

It can hold quite a lot when in the expanded mode, but it becomes quite compact when in the small mode, so be mindful of what you intend to use it for.

The construction is very good and the materials are wonderful.

Unbelievably high-quality backpack. Very spacious. Exceeded all expectations. Bought for a vacation.

Unrealistically high-quality backpack. Very spacious. Exceeded all expectations. Bought for vacation.

Great backpack and excellent quality

I am impressed by the quality, a solid backpack. I spent a long time considering the size, the 37L option fits perfectly with my height of 181 cm. The size is ideal for me, exactly what I was looking for for 2-3 days of travel. I can pack comfortably. I recommend it.

Very nice and quality wise very good also quick delivery. Thanks

Backpack of exceptional quality and size. I've managed to fit a whole lot of things inside and it was still not fully packed. Good materials, nice colour, really good thing to have. Organized well, looks fine, month of use and nothing to complain about. Was a bit scared about the looks on the back, but even on my medium height backpack doesn't look too dig.

Great quality and cost-effective

Good quality
Big size /plenty pockets to feed anything from water to laptop....
Come with the wire just need a power bank to plug in.can be wear as back pack or carry as a laptop bag
Well designed

High quality. Strong material and seems durable, as good or better than my Dell backpack. Great for my domestic flights in Brazil to carry only this backpack or optimize the number of items in my carry-on suitcase (this backpack). At 37L it's already large and a good size. I believe if it were the larger size it would be excessive.

It's really worth the price, I didn't find it cheap, but it delivered everything I expected. Regarding durability, only time can tell. The 37L one has the size of a regular backpack when closed, it doesn't feel awkward on your back, and it seems to be quite spacious when opened. The outer material is quite thick and seems durable, the inner material also seems to be of okay quality. The zippers, at least now while they are new, are very good. In addition, it has a good number of compartments, the compartment for the notebook is slightly padded, and it even has a small pocket at the back where we lean our back, along with a strap to carry along with the bag. The inside cable is UBS A and because it is hidden with a small zipper inside also. The only caveat is that the size 37L does not have a side pocket for a water bottle, but this can be replaced with the front pocket if it's not an issue for you.

Excellent backpack. Well designed, good materials and a lot of space available using it as hand luggage for plane travels.

I have nothing but praise for this backpack. Bange is the best Chinese brand to buy this type of items. It is the perfect backpack for trips with which one can travel everywhere; comfortable, durable, waterproof, and understated, it has everything one needs.

Excellent product! The quality truly surprises, compartments meet any need, and the construction is excellent! 37L is the ideal size for use at university/work as well.

The backpack is really very beautiful. If you intend to use it as a single piece of luggage on a trip, I recommend getting the 37L one, as the larger one is too big for the airplane compartment and there's a risk of them sending it for dispatch.

The backpack is VERY LARGE, I got the 37L one, for me it's the perfect size, it's not so big that you look strange walking down the street. If you need more space, it has a kind of extra that can be opened. The fabric is VERY good, very resistant, beautiful fabric, apparently of quality. I confess it's an expensive item, but it seems worth it to me.
