Quick weight changes
The Loading-Bags for the blackPack models ESY and PRO allow you to quickly change the training loads during your training because you don’t directly fill the blackPacks with Sand or water but the Loading-Bags. Thus, you can easily remove/add a Loading-Bag for every workout and even every exercise and you will always have the right weight at hand. You can even turn your sandbag into an aquabag if you exchange the Loading-Bag SAND with a Loading-Bag AQUA. Every blackPack can hold one Loading-Bag AQUA. Depending on the size you have to use different Bags, ESY L & PRO use the Loading-Bag AQUA L while ESY S and M use the Loading-Bag with the corresponding size.
High quality and clever design
Of course, the Loading-Bags are designed for tough conditions. The Loading-Bag AQUA has additionally glued seams to make sure the filling stays inside the bags during your training. The valve of the Loading-Bag AQUA is protected behind a twist cap. The valve itself is opened by pressing it down and turning it. Filling in water is very easy with the included filler neck. By compressing or pulling apart the Loading-Bag AQUA you can adjust the mixture of water and air inside the bag: the more air you add to the water the more space the water has to move during your training and the more instability will make your workouts even harder.
