I mainly wanted a camera bag that doesn't look like a camera bag, or have obvious logos on it suggesting to would be thieves that it may contain thousands of pounds worth of equipment. This fits the bill.The material and construction is generally good. One of the straps on the water bottle / tripod pocket was missing it's partner, so it has nothing to tighten up against. Not enough of an issue for me to bother returning it, but QC may be a little hit and miss on this. Otherwise it seems fine, zips work, plenty of dividers that can be moved around as needed.Have carried a medium sized DSLR, with three or four lenses (including a 100 - 400) in relative comfort all day. I have no doubt it could fit in a full frame model with battery grip too. top compartment is surprisingly roomy for stuffing in a raincoat, snacks etc. Side access is useful as you don't have to take it off to access your camera, however the material is quite soft, so you can't do the zip back up with one hand. So far I've balanced the camera on the bag when swung round in front of me to give two free hands to operate the zip. Works OK but a little fiddly.
