The heavy bag is constructed like a saddle bag; two pockets can be filled with sand or lead shot to provide weight. Each pocket closes with two zippers that open in opposing directions so no sand leaks out. A handstrap on top opens with a side release buckle, lets you securely attach the Heavy Bag to a Light Stand leg.
The bag has capacity of approximately 20lbs of sand or lead shot.
[Note: Sand Bags do not include sand or lead]
