blackPack PRO Sand Bag

The blackPack® PRO is the perfect partner for Functional Training, offering many possibilities for new and effective weight training. Thanks to its unique construction, it provides a training with instable weight and shape, where the weight, i.e., sand or water, moves freely in the device, as well as fixed. It is produced by an innovative compression system.
The blackPack® PRO can be flexibly loaded witih weights thanks to the loading bags SAND. A blackPack® Loading-Bag SAND can be filled with a weight of up to 12.5 kg. The dry quartz sand is recommended for filling. In principle, the blackPack® Loading-Bag can be individually filled with beach sand, blunt (coarse) gravel or even PET water bottles. You can take anything as weight that you have at hand! It is important that the used weight material does not damage the blackPack® Loading-Bags and the blackPack® PRO (no sharp items, materials containing acid, etc.).
