The ZYN BYN is our min grunt sack that's made to hang from your rear view mirror. Now, there's been this picture of a custom ZYN BYN that was built from "The Don" material. This is this product...
The ZYN BYN is about 5.5" tall and a little over 4" in diameter. We have the ZYN BYN next to our standard Lil Grunt sack in the photo above for comparison.
