I was able to test this K&F camera bag for free as part of the Vine program.
Here I share my honest and objective opinion of this product.

The bag comes neatly packaged with a protective film.
The quality looks absolutely fantastic at first glance, and the workmanship is also extremely good.
The material used here is very robust; the camera bag is very flexible and even reinforced in the most vulnerable areas.
It looks absolutely superb.
There's plenty of space in the small compartments for accessories, but the main compartment also has a nice volume thanks to its clever layout.
The bag is worn as a crossbody bag and can be quickly pulled from the back to the chest. All access points are designed for this purpose to facilitate access to the camera and accessories.
There are sufficient attachment options on the outside as well as inside.
For me, this size is perfectly sufficient to carry enough equipment.
In addition to my EOS 80D, it also includes three lenses, wireless chargers, a charger with extra batteries, and a portable camera light. There's even room for my small Hoehem gimbal for my smartphone.

I'm very excited about this bag. So if you're looking for something practical for on the go in addition to a small and an oversized bag, you can't go wrong with this one.
