This bag can definitely can handle a lot. To ensure maximum durability, we used 1050D Military Grade Nylon Cordura for the inner and outer body of the throwing bag, while the handles are enforced with a flexible tubing for a good grip and handling. To keep this strongman equipment tear-resistant, the seams are quadruple stitched with bonded nylon threads. On the white patch on top of the flap you can label the sandbag with your inserted weight. If you have several sandbags, this is especially helpful for fast recognition in training.
This throwing bag is not exclusive for Strongman training. If you workout with kettlebells, perform goblet squats, Turkish get-ups, snatch, clean and press or rows, to name just a few, you can do them with this sandbag and add some variation to your specific training routines. Because of its handy dimensions, it is suitable not only for commercial gyms, but also for smaller spaces and home gyms.
The most common filling is simple coarse grained sand, but you can fill it with whatever you have at hand. The built-in funnel makes it easy to fill and empty the throwing bag. Once the desired weight or amount of filling is inside, the bag is closed with a three-step system: first, you seal the funnel with the hook and loop closure, fold it down and stuff it back into the sandbag, 2nd, you close it with the high quality YKK zipper and lastly, the super strong hook and loop closure strap on the outside is used to secure all of it in. We recommend a maximum weight of 70lb to be filled into the bag.
