I went to this setup last year and probably will be with it a long time.
Trophyline Platow pack with an academy gamewinner folding seat clipped into the top clips. It holds my calls, binos, thermacell, gloves, mask, extra shells, a snack, and water with no issues. It is quiet to slip off when I get to where I want to setup. It carries like it is not even on my back when I am moving.
If the hunt turns into a game of cat and mouse, then I just leave the pack and seat in the middle of an opening where I can find it and go on hunting with a cane yelper around my neck and my Bobwhite.
Prior to the Platow, I used an Alps satchel/bag that I liked a lot as well. It is lite, doesn't hold too much junk, yet holds just what I needed.
