Several years ago Filson sold a game bag (style 16020) no exposed metal or anything that could damage the finish of a gun. It’s perfect: two bellows pockets on each side (one one each side with shell loops). Easy to slip a bird in through the front. Big enough to carry plenty of ammo, a water bottle, leash, multi tool, compass, and more without feeling bulky. Of course, as is always the case it was discontinued. Too bad.
I’ve worn mine to the point that I’m going to have to send it in to them this winter to have it patched along the bottom.
