The blackPack Loading-Bag AQUA lets you put a weight between 2 lb. and 66 lb. into your blackPack. The freely adjustable ratio of water-to-air adds instability to the training weight causing your muscles to work harder when performing any blackPack training exercises. The extensive workout of the muscles is enhanced by the simultaneous training of muscle coordination.
