I noticed that my Zucca Inferno which I've used less than 20 times and my brand new with tags Paradiso Zucca are losing shape. The bags are lined with some type of plastic or wiring to help them keep shape and now the bottom and side lining look like they are wavy. Like they got bent out of shape. I tried to stuff them so they would get their shape back but they still look funny. Has anyone else noticed this on their Zucca?
