The Three 25 lbSandbags with Wheeled Case from Porta Brace is an easy way to transport stabilizing sandbags from location to location. The combo includes three double-lined, saddlebag-type, sandbags with handles. The bags are sent empty to minimize shipping costs and give you a choice of weighted material such as sand or lead shot. When full, you'll need the included wheeled case to transport them quickly and easily. The case is made from water-resistant 1000D Cordura nylon material and has a waterproof, anti-skid surface on the underside.
