I gave a serious breakdown of the lat bag in a thread "does anyone have this bag"
I've heard alot of talk but haven't seen any bag compare as far as storage without being a backpack. I currently am holding 20 plus 4 towells in the main, a glow set in the side pocket, a hooded thermal, rain shell, gloves, and spare socks in the other. There's full size pencil holders and a Velcro pocket that holds my uv light, it's a lil taller than an energy shot. The front pocket holds my snacks and iPhone but could hold discs. I've tried many different set up depending on the round/rounds.
