i have a Beretta waxed cotton game bag/shell pouch. Had it for years. I liked it better than the Filson one because the bags slide on/off the belt. I'm on my third belt as buckles break and holes wear out but the pouches are still great, i just keep them waxed and cleaned out good, it's been bulletproof. It was about half the price of a Filson. Not sure they make them anymore, this link says "discontinued".

Don't the belt kind weigh down your pants with all the weight?

if you were to try and tote a limit of birds and a box of shells in it, sure. But the places and types of dove hunting we do, you are never that far away from a vehicle so its easy to unload birds every so often. I also use a separate belt for my pants and use the bird bag belt above it. With the three pouches, I can keep shells in one, empties in the other and birds in the back. I also have a stool with a insulated pouch that's good to keep a couple of beverages in and a big ziplock to unload birds in if i'm a good ways from the Ranger.

Still use my Browning Game Vest, circa 1985. Has lasted well & still retains its color.

This. Worth it.
