I've been thinking of making my own but for now I use an old Brit combat jacket that has big enough pockets for most of my crap and a small backpack.
I may just sew on a few more pockets to the combat jacket and add a game pocket across the back and be done with it.
There was once a truism among British soldiers that you should be able to live for a day with what's in your pockets and a week with what's in your belt rig. Not sure how that translates with all the batteries and other consumables the troops need today.
