I liked this shoulder bag because:

As you can see in the photos and in the video, it is a very practical bag to carry as a shoulder bag and you can fit quite a few things, not just the camera and a lens, you can even put your mobile phone and wallet in and have all the pockets free, or you can put another lens, even a telephoto lens.
The only drawback I can find is the colour, but it was the only one left.
The zippers are very smooth and do not get caught.
It is not waterproof, but it is fine with splashes and light rain.

Although the backpack may seem small (capacity 5 L), due to its dimensions, I actually found it to have a good capacity, with an exterior pocket with a zipper, two side pockets where a couple of small water bottles fit well, and a large pocket in the back area.
Inside it has two compartments (one of them is adjusted with velcro) where you can carry even a camera and its accessories, without problem. It has a handle to pick it up and a wide, adjustable strap with a padded area to carry it comfortably.
As for the fabrics, they seemed to me to be of very good quality, resistant and not flimsy at all, and the rest of the materials, such as the zippers, the velcro, or the rings on the strap, are also of quality.
At the moment I am taking it to the gym with the towel and the water bottles (if the water leaks out it does not end up inside) but I have tried it with my camera

The backpack has a considerable amount of padding on all the edges exposed to the outside, including the sides.
The pockets inside allow you to carry what you need for your photographic adventure, allowing you to carry your camera, a telephoto lens and some spare batteries without any problems.
Inside there is a divider with Velcro that allows you to dynamically customize the internal space depending on your equipment.

The materials are also good and the seams are very solid, but I would like to underline the fact that the external fabric is water-repellent, meaning it repels water but this does not make it completely waterproof in case of rain.

Used to carrying small backpacks, this shoulder bag has proven to be very comfortable, allowing me to move it back and forth even with my jacket and without too many acrobatics. Ideal for quickly changing lenses without having to remove the backpack.

The only slightly negative note is the fact that the shoulder strap tends to loosen a bit with these movements.

It's smaller than I imagined, although as you can see in the photos, a Mavic 3 Pro fits perfectly, with its controller and several batteries without any problem and you still have room for some more things.
It's a discreet and pretty backpack that goes unnoticed without anyone knowing that you're carrying a camera or a drone or something similar. Something that doesn't happen with other more professional style backpacks.
Inside it only has one divider but you can put as many as you want if you have other backpacks.
Both walls of the interior are made of velcro fabric so you can configure the dividers as you want.
Inside it has a pocket for a tablet the size of an iPad mini, no more.
Then you have a narrow pocket on the back and front.
The big BUT for me is the material and the color, it gets dirty just by looking at it!!!
A very versatile little backpack!

■ WHAT YOU GET
The K&F backpack packaging is a cardboard box with the brand printed in black. Inside the box, wrapped in a translucent plastic with the brand printed on it, you find the beige backpack (as I requested). The label has a few pages with information about the backpack and possible uses (inside there is a movable part that you can move and fix thanks to Velcro), components, measurements and warranty. The first impression is that the backpack is of quality, it is compact and has several spaces (two side, one back, front pocket with zipper, inside it has a central space with the velcro piece, as well as three compartments: two small side and one flat one in the back that would fit a not very large tablet.

■ IF YOU USE IT...
√ The backpack is ready to use. It has a comfortable capacity to carry a reflex camera (it is not designed to carry very long telephoto lenses) and accessories to a certain extent. In our case, my wife was looking for a backpack to carry a Sony Alpha, cards, battery and charger, and she loved the backpack.
√ The shoulder strap is wide and can be easily adjusted, it has a padded protector to fit on the shoulder and not bother carrying the backpack.
√ The warranty period is one year.
√ It has a capacity of 5 liters.
√ Its measurements are 20x13.5x29 centimeters.
√ It weighs around 360 gr., very light.

■ RATING
- THE POSITIVE -
√ Material and quality of the product in general.
√ The design and finish of the backpack is very good, it is nice and elegant.
√ Good capacity for compact photography equipment, up to two lenses would be possible to carry in addition to the camera body.
√ Inside it is padded, it cushions everyday movements, but I wouldn't say it can protect against strong blows.

- THE NEGATIVE -
χ I don't see any problems with its operation or design. However, the strap is thin and perhaps it would have been better if it had reinforcement or a double strap, however, it fulfills its function.

■ I RECOMMEND IT FOR...
√ Use on a daily basis, as an accessory to carry the camera while you work with it. It is interesting that it is a shoulder bag because you can carry it with the load on your back or put the backpack on the front while you take photos, having memory cards and batteries at hand.
√ It is also useful for carrying other lenses and giving it other uses (for day to day, carrying a small laptop or a tablet), it is not a specialized product for photography per se, but we have seen an interesting and comfortable use for it. 100% recommended.

K&F Concept has satisfied my tastes again with this small shoulder bag to carry our camera along with one or two lenses.

After taking it out of the box in which it is delivered we see that it has a nice design and that off-white or bone color makes it even more attractive, at least for me.

The shoulder bag has a zipper that when we open it gives access to a spacious interior, in which a camera with an attached lens will fit perfectly and if it is not too big we can even put one more, in addition to the most basic accessories such as the blower knob, SD card holder, batteries, etc.

Inside we can distribute the space by means of a separator with velcro to adapt it to our needs or leave it if it is there, that is up to you to decide.

On the outside on both sides it has some pockets to put more things, such as a small bottle of water or things like that. On the back side facing your body, there is another pocket without a zipper to put a small tablet, an 11" iPad PRO doesn't fit by a little, a couple of cm, but the iPad mini does, I'll give you these examples so you can get an idea of ​​the size.

The use that can be given to this shoulder bag is for those occasions when you go out for a walk with your camera and if you see a situation that is worth it, you open the backpack, take out the camera and immortalize the moment, nothing more.

I hope this review has been useful to you

The bag is well designed and provides ample protection for your camera and accessories thanks to its thick interior lining and modular dividers. They are easily adjustable to fit the size of your camera and lenses, making it convenient for a variety of tasks. The material of the bag is highly durable and water-repellent. This is especially important for filming outdoors or in unstable weather conditions. Thanks to these features, the bag will protect your equipment from moisture and damage. The compact size is ideal for photography and light travel. Despite its small dimensions, it can hold a camera, one or two lenses, and small accessories. This makes it an optimal choice for short photo shoots. The multiple pockets, both internal and external, add convenience when it comes to organizing things. They can store cables, filters, batteries, and even personal items such as a phone or wallet. The adjustable strap ensures comfort even during long periods of use. It distributes weight well, which is especially important if you use the bag while hiking or traveling. The stylish and versatile design allows you to use the bag not only for your camera, but also for everyday tasks. Its aesthetic appearance makes it suitable for both men and women. The zippers have a limited opening angle, which can make it difficult to access the equipment. This drawback is especially noticeable when you need to quickly remove the camera or accessories during shooting conditions. The light color of the bag is not always practical. It gets dirty faster and requires more frequent maintenance, especially if used in active outdoor shooting conditions.

Practical, multi-use bag, waterproof fabric and nice khaki green color.
Size 20cm wide by 30cm high.
Very strong and thick shoulder strap, comfortable to use.
A velcro separator is also supplied with it, so several storage combinations remain possible.

Although you can store a camera with one or two lenses, I think it would have been wise to provide an opening on the side to place and/or retrieve the camera, rather than having to go through the top of the bag.

Also, I have not found the ideal location to store both a hybrid camera including an 18-150mm lens and another 85mm macro.
Either I store them diagonally or vertically, but not great, I have the impression that nothing is wedged correctly as desired.
So during my day trips, I only take the camera with a single large lens.

Otherwise nice to add a tablet.
In summary, good multimedia bag but could do better…

The shipment was fast as always, the package arrived intact and well packaged. It is a travel bag.

PACKAGING AND BOX CONTENTS:
The product arrives in an anonymous plastic bag.

DECLARED AND/OR FOUND CHARACTERISTICS:
• Brand: K&F Concept
• Material: fabric
• Dimensions: 20x14x29 cm
• Closure: zip
• Adjustable straps
• anti-theft pocket
• waterproof
• made in China

COMPOSITION:
The backpack is made up of the following pockets:
- one in front with a zip for objects such as a mini tablet or an eBook reader or accessories such as a power bank or hard disk.
- a large pocket for objects such as clothes and if you use the divider provided in the package for a camera, or for traditional bag objects;
- a small pocket on the back to hide valuables such as wallets, keys, documents, etc.
- on the sides there are two pockets for water bottles and umbrellas.

The straps are easily adjustable to fit all heights.

OVERALL CONSIDERATIONS:
Aesthetically the backpack is very simple and has a clean look and is also suitable for travel.

The fabric is waterproof and water resistant and the cut is made to be carried over the shoulder with the bag still on the chest (or behind the back). Perfect for chaotic trips to always have the bag in the front to keep under control but at the same time leave your hands free.

The zips slide smoothly and the strap adjustment is successful without many problems. It has never happened to me that the shoulder strap, once adjusted, lengthened by itself during use.

Honestly I have not used the bag to carry around the camera but I have used it as a simple travel bag therefore filling it with classic objects such as wallets, hand gel, wipes, sunglasses, powerbank etc and I found it extremely roomy.

Finally, the pocket that I found very convenient for travel is the anti-theft one, hidden on the back of the backrest, which I find perfect for keeping wallets, documents, keys and AirPods safe.

I found the side pockets suitable for a small travel bottle and an umbrella and I found them convenient because the object, when inserted, remains perfectly still even when I happened to have to run.

I washed the backpack in the washing machine with the synthetic program at 30 ° and there were no accidents: it did not discolor, the seams were not worn, the zips are intact and the padding was not ruined. Obviously it must be left to air dry.

Good quality-price ratio. The materials are good and the seams are well done and I found the backpack really functional. The price of about € 40 (at the time of the review) I find slightly high compared to that of other products of the same type on a par with features and functionality.

I hope that my review can be useful to you and ... happy shopping!!
