Well, the material is the same as the covers for the Q-Series Grill's. Robust. But when the size is unfortunately what went wrong. The case fits at all. Hangs like a rag around the bottle, which also sticks out a bit above. As one would at Weber times to explore the German market better. But I keep the envelope anyway, because the bottles are partially rusted from the hardware store and I did not have to see these places. If there is even a matching envelope, but I will be happy to access again. So if you want to cover his rusty gas cylinders and not look carefully the envelope can control who does not want should stay away from here.
