The Ultimate Sandbag is designed to meet the demands of elite strength and conditioning needs. The Ultimate Shell comes with 7 handles as well as a non-abrasive outer material that allows trainees to grab onto the shell itself. The Ultimate filler bags provide the weight to the bags. The small filler bag provides 10-20 lbs and the large 25-45 lbs. This allows variable resistance to fit the need of any trainee.
