The first thing I like about this K&F Concept bag is the appearance due to the fabrics used. The tweed style grey panels paired with simple black for everything else in about equal measure makes for a sophisticated bag. This product would blend in for situations where you want a back pack's functionality without the image of an outdoors hiker.

It has all kinds of zippered access points to the main section, plus several compartments inside and out that you (and pick pockets) might overlook at first because of where they are placed. The zippers have tag ends of round cordage that end in peanut sized plastic 'buttons.' Unfortunately my sample had one of these already separated and loose in the shipping bag on arrival. It had not opened up. It and the cord didn't have a good join for some reason and slipped apart I assume. A few minutes of DIY to pry open the button, insert the cord ends and squeeze it very hard with sturdy pliers to get enough grip got it back to appearing to function again. It was an odd distraction to otherwise being pleased with the construction of the bag.

There is an image on the printed contents of a strap with plastic buckle crossing the front of the chest, connected to rings on the big shoulder straps. My package contained no such cross strap and there is no other indication that it would normally be part of the contents. There was no rain cover, which I mention because at least one review mentions a cover. K&F information that I have doesn't mention a rain cover.

The interior is just wide enough to take my full frame mirrorless camera with my 300mm zoom lens attached, situated where it is the main item made accessible from the side panel. My outdoor shooting of recreational events and entertainment venues for years now is centered on switching the one camera body frequently from the 70-300mm lens to the original 28-70mm lens as I move about. I still haven't found or maybe I haven't properly figured out how to set up any bag to be able to do that with the bag still over both shoulders, and certainly never from trying to reach back around my left side to open the access panel. I also keep wishing these side access cavities were given some commitment to being a reinforced horizontal space so they don't buckle under the weight of a full frame camera and medium to large lens. The insides don't have to be so free form in my opinion. Or at least include a variety of hook and loop soft panels so rigid box shapes can be made from them.
