Meet the D-Ball SLUG: a core training buoy bag that you can use for carries, lifts, drags, throws, and MMA style ground & pound. Its weight ranges from 50 to 150lbs, so it can test athletes of various abilities and strength levels. It has a molded marine-grade vinyl polymer surface, so you can use it indoors and outside.
A mixer of 6-7 fill materials is used inside each buoy, including walnut shells, sand, and steel shot. Each buoy bag measures 31 inches long and 11 inches in diameter.
