Where's the down?

I ordered these for my daughters for Christmas and was very disappointed when they arrived. I was prepared for the awkward ties from the reviews I read but I have no idea how the reviewers raved about how warm these were. They are so thin I can barely tell there is any down present. I had to put it on over a sweater to be comfortably warm. I was hoping for something lightweight but warm they could wear around the house instead of a sweatshirt. These are a joke-stick with the sweatshirt or fleece.
