After trying the plastic and fabric pockets, I wanted to try silicone. A real discovery! The pocket is rigid it takes flexible it takes. Does not stain, wash in a jiffy and dries very quickly, do not take the smell. I do not understand how I could fight as long with other types of pockets or why everyone does not use this material everywhere. My only regret is that the hole was already done, and is very broad. So I had to buy an adapter for nozzles to put those I had already (another brand) that were not as wide at the top. I recommend, rent, advises, in short, do not hesitate.
