I picked up a Filson "Tin Cloth Strap Vest" last fall and it is closer to perfect to my needs than any other vest I have tried. No metal buckels to scratch a gun and not a piece of plastic on the garmet. Probably as close to what you would find on a truly vintage game bag as there is.

Not inexpensive but worth the price.
