Use the backpack now for quite some time and can therefore give you some feedback about its quality. Backpacking, that you apologize in advance, I am completely satisfied. It meets my expectations totally, she even at times exceeded. What I've been looking for, was a convenient way and White to transport my become larger photo equipment over long distances. This is possible with the Flipside 300. In addition, the flipside is comfortable to wear and can accommodate an average sized photo equipment consisting of several lenses, accessories, memory cards, batteries / accumulators, filters, etc. Access to the equipment I find uniquely good. By rotating the backpack around its own axis, supported by the waist belt, you can access the photo equipment without having to turn off the backpack. So you can even in lenses run wechseln- But always keep an eye on the environment, otherwise one runs fast irgentwo it! Super I find that one with an attached backpack does not have access to the camera equipment. This made me even before min. a long finger, or a Langfingerin preserved. On a trip with a group stood on the photo suddenly an unknown person next to me who recognize themselves in the picture considerably, apparently interested especially for my backpack. Goofy just that they apparently had not found the zipper so that it was no longer in the next group photo, which was taken only a few moments later there. Scary story, I still runs a shiver down my spine when I tell you. So overall a great backpack, if you want to take bears solely his photo equipment comfortably and safely. For supplies, or the like (for me at least) little space, but that does not bother me.
