PROS:lightweight, can easily take on/off using the buckle, affordable, weather proof, good compartments, compact, can also wear with a purse, stows nicely in luggage or under the airplane chair, and can tether your tripod to the back with the straps, adjustable compartment for various cameras. Best PRO: hands-free hiking, cross-body stabilityCONS:can't carry more than one lens, is not a backpack, won't feel like it's sturdily "on you" unless you buckle the whole thing together (if you don't it just rests on one shoulder and you have to use the same hand to hold the strap, kind of like carrying a backpack on one shoulder only, and if you lose one or both of the tripod straps you have to buy another. Though the ones they give you are kinda wimpy but you can easily purchase thicker sturdier tripod straps. It also makes your gear a whole lot heavier with the tripod in the back.
