The "sand sock" is the perfect size. It holds completely the butt stock and its of ample size for my hand. It's easy to manipulate - squeeze or relax. The consistency of the material inside the bag is exactly as it should be, along with durable material holding it together. The small loop was a great addition so it can be hooked onto my belt or attached to the rifle. The end result: I am able to maintain a rock steady sight picture of my target until I squeeze my trigger.
