How many times have you needed a sandbag, but found it was too heavy to fly with, so you purchased one locally and left it on location? The Orca OR-83 Sand/Water Bag was designed to help carry sandbags to any location, with an option to then fill the bag with water or sand. The bag is made from one cavity of durable tarpaulin material with a binding strap, so it is easy to fill with sand or water bladders.
The OR-81B Water Bladder is sold separately and can hold up to 4 liters. We use two of them to fill the OR-83.
