Mine doesn't have a particularly soft lining. It has ties/clips that go under the car.
I'll get it out, but if i remember correctly its a woven cotton type material that is coated on the outside in a rubbery/plastic silver finish. It has a storage bag made out of the same.
my sister lives in Thorpe astly but works in derby with me everyday. I'll get it out at the weekend to make sure the condition is ok and can give it to my sister next week if you want.
