I must say I like this bag, I have six of them. The build is above average and more than adequate. I purchased the first of these bags four years ago. It has been subjected to moderate use and is still intact, i.e. no rips or tears. The zippers still work as they should.. The features that most impress me are ease of use and comfort. If you lay the bag on its backside and open the one large flap on the front you have easy access to all of the bags content. You can retrieve what you want without having to rearrange the rest of the bags content. Another feature that I like is an empty bag has sufficient integrity to stand on its own. The rear computer pocket will carry a 15 inch laptop with ease. It is not large, but will carry one or two camera bodies and two or three lenses. In my main bag I generally carry two Sony Alpha 7CR bodies, a Sigma 14-24mm F2.8, a Sigma 24-70 F2.8, and a Sony FE 100-400mm F4.5 - 5.6 GM, a Sony GN46 Flash, four additional batteries and a small battery charger. Its tight, but it gets me to where I am going. The other bags are used for other photographic needs, i.e. Macro, Telephoto, and cinematography/videography.
