Update: It has now been over 6 years since I bought this backpack! I'm finally ready to buy a new bag, but this thing held up wonderfully. I'd have never expected a $50 camera bag to last this long with nearly daily use. Let me tell you what broke, and why I'm looking at other options, but before I do I should clarify that this is still a five-star product due to how long it lasted.Failure points:The fabric dividers have started coming apart. The stitching holding them together simply couldn't take any more abuse. I've dealt with this for a few months, but the final straw was the zipper breaking on one of the side access flaps.Design flaws:1. The straps have WAY too much length to them, and not enough options to retain excess material, meaning my bag has always been covered in hanging strap excess. You could tape things up, but that would only be putting a band-aid on the problem.2. The divider pads are too soft, and they give way very easily. Often my equipment would end up jumbled, at least after the first few years of use.3. The shape of the top zipper enclosure is just silly. The way that it flairs out makes it floppy and annoying to deal with one-handed.4. The top compartment has inadequate pockets for keeping items organized. It just wound up as a jumbled mess in the end.5. Some of the outside (side) pockets are uselessly small6. The tripod holding system is junk. I wouldn't keep a $10 monopod on there.With all that said, it has survived to this day. If I can't find something else with the convinient quick-access side and similar size, I'll probably just buy another one of these.Original Review:I've had the Vivitar for over three years now. I am a professional photographer (or at least, people pay me to take pictures and it is my only revenue stream) and this bag goes to every shoot. I've only now started to see some wear and breakdown, which is a damn long service life for such an inexpensive bag.About the bag:I can carry a 5D MK3 (with or without grip) along with my flash, a 70-200 L and two normal sized lenses (a 20mm and a 17-40). I also carry 6 batteries, extra memory cards, a laser tape measure and lots of odds and ends. I can even stick a good sized tablet or small laptop in the provided pouch.The big selling point for me with this bag is how you can sling it sideways on your front and pull your camera right out, ready to shoot. The top access works great when you use it like a normal bag and set it on a table to switch lenses.Pros:+Strong handles and straps. They're all still in place and working+Comes with a rain cover that doesn't cover the straps, so you can keep on trekking+Plenty of little pockets and spaces for various things, including zipper closed netting pouches in the top segment+Tough enough for regular use. I wouldn't take it on lots and lots of outdoor shoots, but if you shoot indoors, it stands the test of time+Small and compact enough to not look like a paratrooper when you're walking around+Good strong zippers, no problems there! All the zipper pulls are still intact too+ComfortableCons:-The dividers are flimsy, as with all other camera bags I've used. They still work though-The monopod/tripod holder is only good for small, light units. It won't carry anything I own. The strap for it also has little resistance, allowing it to come lose.-Because there are three sides you can open, sometimes I would forget and leave one open, though somehow none of my gear has fallen out yet. I know this just sounds like me being an idiot, but if you do this work day in and day out, you're bound to forget some time.Summery:If you need a relatively cheap bag that doesn't carry a whole bunch of lenses and you don't shoot professionally outdoors, this bag will probably work for you. If you are a hobbyist of any kind, this thing might last you a decade.
