Ideal for competition use or training, our new professional quality tunnel sandbags are made from heavy-duty PVC-coated nylon and are available in two colors. Each bag will comfortably hold approximately 30-35 lbs of sand and measures 12"W x 6"D x 16"H. They are connected over the tunnel by a durable 2" wide nylon & Velcro® strap for quick assembly and adjustments. Adding sand is also easy through a large top opening with Velcro closure. One pair of sandbags hold one end of the tunnel. Sand is not included; tunnel shown in photo not included.
