We have a Kampa breathable awning carpet quite pleased with it, yes it is a woven type of plastic and can be a little slippy if you are in your stocking feet or if a mat/rug is placed on top. We did get a few mud patches this year but how many did not, at home hung out over clothes line and hosed down, left to dry and packed in its own bag ready for next time. Oh I forgot to say had no bugs crawling through and grass looked OK afterwards apart from late August when we had the heavy rain and the mud. Think it was only 40 something quid from United British Caravans and 5.5 metres long
