fllece didn't come into being until recently, polar fleece is recycled soda bottles melted down and spun into a thread that is then woven. that's why it dries so quickly. I know the kind you're talking of. I had one 50 yrs ago when I was about 5 or 6. don't know what they are made of. didn't interest me at the time, but I knew it was midweight, under my quilt and over my sheet.
