Very convenient to take several photos in cameras: Can I put a Sony SLR + 1 Canon DSLR canon power shot, and even 2 small bottles of water.The multiple pockets for storage are all identity documents, credit card, check book, topo map of the hike or IGN mobile, user manual of the device pictures ....... I use it for trips of 2 hours approximately. For longer and more acrobatic rides, I carry one device to photograph (the Sony with zoom x 30 with different modes for shooting) and a smaller bag because the strap hurts shoulder , because of the weight and the volume of the bag can interfere in the movement, except for some large .J'aime its sober and elegant design and I sometimes use it in handbag!. ..... may be perfectly suitable for photo reports, downtown, tourism situation! .. Appreciable, the waterproof cover incorporated under the bag, although I'm not yet used it ...... This bag is recommended for short trips, otherwise, do not over load, even if the strap is wide and well ...... reinforced solid Product appearance and good quality. Recommended! Shipping and packaging impeccable !!!!!
