It seems to be well-made. I have not used it yet, as I purchased it to use in the summer. The tag says it is at least 50% down. I was a little disappointed it wasn't all down, as the product details on the Wayfair's website just states that the fill is "Goose Down". Looking back at the description, I do see that it says "filled with the white goose down blend". It still seems to be a good product. I like that it has corner tabs to tie my duvet cover so it will stay in place.
