I am on my second season with a Summit. I can't remember exactly what came with it, and what I ordered extra. I know I added the extra bag to go on the back. And I have 2 water bottle holders. In the extra rear bag, I carry a bunch of dog first aid supplies. I carry cable cutters in the main back compartment. I have an extra side pouch that I carry an extra pair of gloves, and a thin neck gaiter and stocking hat in. I have no doubt that this will be the last vest I ever have to buy. Very well built. I'm not super flexible, but I can easily load and unload birds with one hand. I keep a collapsible dog bowl and slip leads in the game pouch and can easily get to them without taking the vest off. The only thing I don't like about it, is the shell pouches can't be zipped or unzipped with one hand...at least I haven't figured out a way to do it? This isn't a huge deal for me, as I rarely zip them. When I take the vest off I hang it from a cargo hook in the backseat of my pickup.
