I tried several camera backpacks in the last few days and am at the end of almost desperate. Admittedly my expectations were quite high. Accommodate a DSLR with two lenses and accessories should swallow the backpack. For this purpose an extra pocket for other things that are needed on the road. Purse, cell phone ect. And a tripod mount had to be there also. Of course, everything Waterproof, yet not so huge. After several backpacks I actually thought about giving up already but the Cube Challenge I wanted to test yet. In short: I'm surprised! The backpack can accommodate everything above enumerated, is processed very comfortable and very high quality. In the upper compartment they even give you a small vest or sweater under when it gets a little too warm on the hike. The weight of the backpack spreads pleasantly on the back. Easy to carry even on longer trips. Auserdem surprised the backpack with lots of little extras which are missing even in expensive well known manufacturers. Example White small rubber bands with the help of the waist belt can be rolled compactly when not in USER. To disturb the two ends while you are walking by constantly anbommeln on the legs. I would choose this backpack again!
