After more than a year of use, this bag isn't showing any obvious signs of failure. I got this bag primarily for it's size, since I guess I have a problem with gear acquisition. Currently it carries one DSLR body with battery grip, and another crop-sensor DSLR, an 11-20mm f/2.8 lens, 17-50mm f/2.8 lens, 70-200 f/2.8 lens, 150-600mm lens, 35mm Macro and 90mm Macro lens, 1 pancake prime lens, and a 50mm prime lens, plus filters, 12 batteries, a charger, compact tripod, remote shutter, rain poncho, and various other minutiae I'm sure I've forgotten, all internally, sometimes with a little effort. Despite pretty much over stuffing it, the back of the bag stays flat and comfortable against my back. The shoulder and waist straps are wide, soft, and comfortable, despite the heavy weight. The side pouches and straps work well for carrying larger items like full size tripods, monopods, and even my travel stool (though I do wish I could release the side straps with a buckle, to more easily retrieve items without taking the bag off my back).Dividers inside the bag are good quality and protect my gear well, and I haven't had any issues with moisture making it inside the bag either when it rains, though I usually cover myself and the bag with my poncho once that starts. I haven't had any problems with stitching thus far, and that's despite attaching a Peak Design QR plate to the left shoulder strap and regularly hanging more than 7lbs of camera+lens off it.My biggest complaints are about the design; I'm not sure I find much benefit in the upper and lower sections being separate, and wish the interior was instead one contiguous compartment to allow better versatility, and I wish the back opened for access to equipment. These were things I knew purchasing the bag though, it's kind of hard to find a camera bag that ticks all the checkboxes on my wishlist, and they're not big enough complaints that I feel the need to replace the bag either.Unless I find the magic camera bag that does every single thing I want, I expect to still be using this bag in five years, based on it's service thus far. Overall I'm very happy with it, and with my ability to fit everything I want to bring with (which is almost certainly far more than I need to bring) relatively comfortably.
