Hello everyone,
This K&F Concept photo backpack was kindly provided to me free of charge as part of the Amazon Vine program, for which I would first like to thank Amazon and of course the manufacturer.
The fact that I received this product free of charge has no influence on my rating!

So I'll say it right away, in my opinion this K&F Concept photo backpack is a very typical photo backpack, which is solidly made and offers a lot of storage space, but unfortunately does not have any special features beyond that.

As usual, we have various dividers here that can be flexibly aligned. Both in the upper and lower areas of the backpack. Alternatively, the separate lens bag, which is also included, can be stored in the lower area. This can also be equipped with a shoulder strap if you like, so that you can carry it separately and use the lower area of ​​the backpack that is freed up as additional storage space.
The small lens bag offers space for two lenses (depending on the size) as well as some storage space for small items.
The backpack as a whole is of course very bulky, weighs over 2kg when empty, but offers a number of storage options. There are side cup holders, which can of course also be used for compact tripods thanks to the tightening strap in the upper area. It offers many small pockets in which various accessories can be stored. In addition, it also has a hip and chest strap. The hip belt has two small pockets integrated, which I personally always find very practical, for example to quickly access everyday items.

Less practical, however, is that the hip belt unfortunately cannot be removed. In my experience with other photo backpacks, this is usually always possible, but unfortunately not here.
There is also a pocket on the back that can be opened from the side for a laptop, for example. I don't like the concept here. Because if you want to open this bag completely with a zipper, the straps are always in the way. This is a very unwise design (in my opinion).

I really like the fact that the front main compartments can be opened completely. This makes it easier to access the equipment and offers more space when packing and unpacking. The smaller front pocket for the main compartment, which can also be opened completely, also has two Velcro compartments, although these are upside down when opened. It doesn't make sense the other way round either, as otherwise they would always be upside down when closed, but I would have preferred zippers here for more security - so that nothing can slip out.

Otherwise, the backpack is mainly equipped with zippers, so why not here too?

The zippers themselves all close very smoothly and reliably. It is nice that they all have grip sleeves, which makes the pockets easier to open.

Other positive points in my opinion are that the backpack is generally very well made and also impresses with its solid material quality. It can be placed down stably and also has acceptable protection from the ground. The material is 600D waterproof, the upper zips are covered with overlapping rubber and there is also the obligatory rain cape, which I think is super easy and quick to put on. I have had much worse experiences with other rain capes.
Another positive point here is that the height of the straps on the back can be adjusted to three different levels (L, M and S).
This logically leads to more flexibility in terms of comfort.
The comfort as such is very good in my opinion. I personally find the backpack very comfortable and thanks to the chest and hip straps it sits sufficiently stable on the back.

What I personally miss about this backpack is quick access to the camera. Many photo backpacks allow quick access to the camera without having to completely remove the backpack. That would be something that I would generally expect from such a well-known brand and the price asked.
Since you know this before buying and everyone can decide for themselves whether they need such a function or not, this should only be understood as a hint and not as a point of criticism.

[Conclusion]:

So all in all, in my opinion, you get a rock-solid mid-range photo backpack that is certainly convincing in its core competence, but beyond that, there is little that is special or even innovative.
ative that would perhaps set it apart from other typical photo backpacks. Only the height-adjustable shoulder straps are perhaps something that you don't find on every photo backpack.
The quality of the materials and workmanship is high for the price and you can assume that the backpack is very robust and you will therefore enjoy it for a long time.
In my opinion, the type of backpack you are looking for is crucial when considering a purchase. If you just want a good quality, rock-solid, comfortable "standard" photo backpack with plenty of storage space, then in my opinion you can't go wrong with a purchase here. For currently just under €160.00 (RRP €200.00), you get a very good price-performance ratio.
However, if you want to be even more flexible in everyday life and also value quick access to the camera and need a lot of freedom in terms of design options for packing photo equipment, you should take a close look at this backpack beforehand and then decide whether it is enough for you. Because it is generally very subjective how you like to put your equipment together and pack it. Personally, I don't really like the options available here, despite the flexible divider design. I find access to the pockets just too complicated for my taste.

But as already mentioned, that's just a matter of taste.

Generally and objectively speaking, this is a very decent photo backpack that hardly has any weaknesses. The only thing I see as a clear criticism is that you can't remove the hip belt.

In conclusion, I give it a good 4 stars!
