Previously I used a camera bag from Hama. Also large and super processed. But not necessarily appropriate due to the size of outdoor activities. For transportation to a location ideal, but nothing to wear long. In contrast to the Bilora. Once the beams are set and the optimum carrying position has been found the backpack is really comfortable to wear. And the heavy weight. For me there are two Canon 5D or 50D - each with battery grip - and 6 lenses (including 3 heavy L), flash and much incidentals. Add to that a Cullmann Magnesite Tripod with Ball Head Eiger. And the holiday is still to a 17-inch notebook. All in all, then about 20 kg. But portable and not to be compared with a normal camera bag. The only drawback is the lack of Velcro, holding the camera and lens firmly in his pocket. In contrast is the absolutely reasonable price. For me and my requirements so clear 5 Stars.
