You can choose between sand, steel balls and water. Depending on the nature and quantity of what you put inside, the amount of air contained inside the bag varies, thus also varying its level of instability. Another advantage of this sandbag is its handles: attached to the side of the bag, they don't come into contact with the body and therefore don't interfere with training. Particularly robust, the seams withstand the most intense stress and are waterproof. The double valve allows quick filling and emptying.
