tried this bag slung on both the same shoulder and the opposite shoulder, while walking through streets and hillside trails. The opposite shoulder is probably the only way to carry it for more than a few minutes. Trying to keep it from sliding off the same shoulder took more concentration than anything else. The finish on my parka is pretty much the same as the K&F Concept Sling Bag. Both are designed to repel the elements and prioritize function over fashion. That said, the K&F Concept Sling Bag has a refined, not “techy” appearance and won’t draw much attention to its contents. The interior is fully lined with soft protective materials. It looks very narrow upon arrival, but after working on the sides for a few seconds, the overall width is established. The included divider panels can actually be about 1cm wider than they currently are, to help separate the side walls. As you can see in one photo, I was able to drop it into a Sony Alpha body, in a cage, with a 28-70mm lens attached. Next to it I placed a 17-28mm lens and on the end is a 70-300mm lens. With a little effort I could probably fit a speedlite in, but it would no longer be a running and gun bag, but more like luggage. This bag could be a solution for people who like a hands-free camera bag but don't want to have a full backpack. That would be me.
