When the package arrived from Amazon, I was first amazed how big the backpack was. When we set for the holiday photo luggage together (SLR with two lenses, flash, battery, charger, monopod, filters, wipes, etc. and a compact camera) all fit easily into the pocket (... and there was an even little space for other things over). Today I would say that less may not be a backpack or camera bag. What has helped me to organize the subjects, was a role double-sided Velcro tape (eg Tesa Cable Manager) - I can now when loaded and open pocket, turn this on its head and nothing falls out! The value for money in my opinion unbeatable - I have the fifth star forgive despite all the - the reason lies in the too small zippers on the zippers (To this day, still is not one of them broken, but I have this also only half a year)
