The invention relates to a covering with a "hook-and-loop" engaging surface for a loose bulk or free flowing medium. One outer surface (2) of the covering (1) is provided with hooks, while another surface (2) is provided with matching connecting elements. When coverings filled with a particular medium are stacked on top of or next to each other, the hooked elements on the surface of one covering engage with the connecting elements on the surface of at least one other covering (1). |
