In that case, I wouldn't trust anything on the label or any of the packaging. If you can swing it, a quality down bag costs more up front but can last decades if you take proper care of it (mainly always store it dry and uncompressed, and avoid folding it). If you're just car camping it's maybe harder to justify but if you backpack at all the weight savings that come with down are really worth it. One of mine is almost 20 years old and still going strong, amortized over the life of the bag it was a great deal back when I bought it.
