Given that there is no "perfect bag", this 10L one-shoulder model from K&F has a cut that lends itself well to multiple configurations or uses... even if I'm always talking about photography.

Speaking from personal and professional experience, I prefer the one-shoulder bag - compared to the backpack - for a question of practicality, speed in accessing the equipment, and comfort in general.

The 10L size is sufficient to reduce the size without penalizing the load. In fact, I can fit in this bag peacefully: mirrorless camera, drone, controller, batteries and various accessories, gimbal in the side pocket. The load is still well protected and accessible during use.

The top pocket is small, but enough for a load of accessories.
The lower one (the main one) can be customized with separators (5 in total) and a comfortable elastic lens holder. The lower pocket is accessible through a convenient shape of the resealable flap which allows access to the chamber without opening the entire compartment.

Among the outstanding points: I'm perplexed about the actual waterproofness... I would have preferred an additional bag cover.
A document pocket accessible from the outside wouldn't have been bad. But considering the 10L size I realize that it would have been a "problem".

The quality/price ratio is very good, which places this model (similar to other more expensive brands) as a valid option in this category of items. K&F is famous for its high quality filters... I hope we have maintained the same care for this bag too :)))

At the moment I recommend it... I like it and find it very well made.
