The BFB (Big Front Bag) is our largest shooting rest bag, tipping the scales at 13 pounds, yet it is still easy to transport. It is designed to be the proper height for any bench shooting or optic support. The pyramid shape prevents tipping under recoil. It's a much smarter design vs. the rectangular shapes out there that tip over. Non-skid base prevents moving around on the bench. 1000-denier material = tough, unlike the cheap material that the Chinese are famous for. It's also tall enough... you don't need to stick a phone book under it to get it to the right height.
