This is a really nice bag for the price. There is a main compartment where the camera goes, with a zipped mesh pocket inside the lid, another big zipped compartment on the front with quite a bit of space for stuff, and two mesh pockets on eider side of the bag. There is another pocket on the back of the bag ideal for paper work or instructions or a note pad.
The main compartment close with a zip, and a overlapping clip.
I feel confident that this bag will give my SLR protection for small accidents, but be careful not to drop it from the hot air balloon, plus I would try to kip it away from heavy rain, it looks like will cope with some water but not loads.
I think that you get a lot of bag for the price.
