decided to try the backpack that was offered to me to test thanks to K&F Concept, and I must say that it is way too big for my needs, but still very beautiful, versatile and robust : I found it expensive but I must change my mind, because it is qualitatively excellent. When I can, I travel a lot, even if only to get to my second home, and then from there I go hiking. If I can, I carry my son's camera, the television, and a light easel, and I'm always worried that something in my bag will get damaged or broken. So I'm happy to have had the chance to try the product, and it is objectively very good. It has a capacity of 25 liters which is basically perfect, it's not too big or too heavy and I still have room for a phone, chargers, power bank, flash and other gear , in addition to keeping the easel attached underneath. It is water resistant and also comes equipped with a waterproof cover that makes it completely safe in the rain, which doesn't hurt in the event of a sudden storm. At the back, in the rear area, the back is reinforced and therefore has a semi-rigid structure that helps protect the most delicate parts. Inside the backpack there are several compartments that allow you to store everything without risking damage. My laptop (I have a 15 inch) fits comfortably there, in addition to my camera with TV, macro and lens, as well as additional compartments in which I place my tablet and external battery, and the strap under the backpack allows you to attach a tripod, just in case, even if it is equipped with small or very compact tripods. Excellent product, really well made!
