The maximum load of the blackPack is directly proportional to its size. The blackPack ESY S, for example, can be filled with up to 10 kg (22 lb), the bigger sizes are tiered in 10 kg steps:
- blackPack ESY S: 10 kg / 22 lb
- blackPack ESY M: 20 kg / 44 lb
- blackPack ESY L: 30 kg / 66 lb
- blackPack PRO: 40 kg / 88 lb
You can also use Steel Shots to keep the volume to a minimum. The maximum weights, however, should not be exceeded. When using the Loading-Bag AQUA we also recommend not to exceed the given weights. Here, you also have to take into account that the mixture of air and water can increase the volume in a way that it only allows lighter training weights. The higher instability in return makes up for the lighter training weight.
