Why would I buy an unfilled bag instead of a pre-filled one?

Unfilled bags are cheaper to ship because they weigh far less. The secondary benefit is customisation — you control exactly what goes inside and therefore control the weight, density, and feel.

What should I fill the bag with?

Start with a firm core of tightly packed rags or sand bags in the centre to add weight, then pack the outer layer with softer foam offcuts or fabric for surface cushioning. Most practitioners use a mixed approach for a firm but not punishing surface.

How heavy should I fill a 5-foot bag?

A 5-foot bag typically fills to 80–150lbs. For general training, aim for 100–120lbs, which provides enough resistance for power combinations without excessive swing.

What ceiling height do I need for a 5-foot unfilled bag?

A 5-foot bag requires a minimum ceiling height of approximately 9–10 feet for comfortable striking clearance at head level. Allow extra clearance for the chain and swivel hardware.
