The K&F Concept camera backpack is big. Very big. A lot of things fit in there, either a lot of camera equipment or a few clothes or something to eat for a trip. The sturdy middle wall allows you to divide the backpack into two parts and use one as a daypack. If you are advanced in dividing up photo backpacks, you can even manage to fit a Sony 200-600mm lens and camera in the backpack, which not many manage.

It comes with a small bag that you can either use separately with the shoulder strap or stow in the backpack. A nice gimmick that could have been copied from another company. The interior is designed in orange, so that you can also easily find small black parts there (for example the classic lens cap and hot shoe cover...)
There are many different dividers so that you can set up the backpack however you want. There are also many different small pockets in which you can stow all kinds of accessories. You can also stow a notebook well. There are a few straps on the outside where you can attach other accessories, such as tripods. There are also pockets on the sides for bottles. There are also two pockets on the waist belt. The shoulder straps on the back can be adjusted to the size of the wearer. This makes it quite comfortable to wear.

The quality of workmanship is not particularly good. In some places you can see that the workmanship was a bit careless. For example, the fabric on one strap is fraying.

You should note, however, that the backpack is quite heavy at almost 3kg due to its size. When fully filled, the thing can become really heavy, so it's not suitable for long hikes.

Due to the weight and the small defects in workmanship, I'm giving it four stars.
