The Avenger G100-2 Sandbag is made of durable black nylon and features a saddlebag design that makes it easy to drape over stand legs or booms. The bag holds up to 13 lb of sand in its two compartments, has a touch fastener closure, and ships empty to allow you to fill it with any weighted material of choice. The bag has a D-ring at each end for use with a hook.
