Very robust - exactly what I was looking for

Since I have found nothing on the Internet found suitable, I have "tinker" decided with this bag yourself the weight. The price of just 30 for me was just OK.
Even When unpacking, I was impressed by the robustness of the material and had no concerns would take to hire such a large load damage that the bag.

The bag I have now filled with 25kg of dried sand game at hardware stores (2).

The long-term practice test see pending. I do not know whether the seams hold or if the bag one year loses its charge. But I am very confident that he can stand it.
