Watch who you call Dummy, Dummy! I just might save your life one day. I'm ideal for rescue training and fall testing. You can fill me with recycled tires or rubber, but I prefer corn flakes - it makes the fall much softer. As the saying goes, It's not the fall that hurts so much, but the sudden stop! I'm made of very tough duck canvas material with heavy nylon stitching. Zippered openings allow access to each section of my body. 9,000 lb. tensile nylon loops are stitched front and back to keep the practice belt from running up my chest. There is also a high back loop for clipping into. I'm shipped without stuffing.
