Ultra Fitness Workout Exercise Sandbags - Heavy Duty Sand-Bag, Functional Strength Training, Dynamic Load Exercises, WODs, General Fitness and Military Conditioning

The Ultra Fitness Workout Exercise Sandbags are praised for their toughness and durability, with a well-made design and strong features such as double velcro seals on the internal bags, sturdy handles, and a heavy-duty zipper. Reviewers report that it is easy to fill with sand or other weighted materials, with sewn-in red thread providing guidance on how much to fill the internal bags. It is said to be suitable for a range of exercises, including crossfit, WODs, and military conditioning. Some reviewers note that sand may leak or spill, and one reviewer suggests it would be better if the sand filler was sealed.
