Join Cathy and Wayne as they chat about the wonderful world of insulated clothing. Learn the difference between feather and down, why "fill power" is a good thing to know and understand why most insulated jackets aren't waterproof. There's laughter, there's techy stuff, there's the word "poofiness", there's an explanation of why you need tennis balls to wash a down jacket and perhaps most impressively, another of Cathy's podcast visualisations!
