Thread: using rear guns bags in the field ?

@rossi.45 one trick I did use before I brought a bag was I got an empty 3 ltr wine bladder. With the thing deflated it takes up on room and once you are in position just inflate it to desired hardness.
Once you want to move let the air out and away you go.
It works guite well and it will let you experiment using a rear bag to see if you will use one in the field.
