A gunny sack, also known as a "gunny shoe", is an inexpensive bag made of hessian (burlap) usually formed from jute or other natural fibers, although modern sacks are often made from polypropylene; the "gunny" portion of the name ultimately descends from Tulu goni. Gunny sacks are traditionally used for transporting grains, potatoes, and other agricultural products. Today they are also sometimes used as sandbags for erosion control.
