Are there real down comforters under $100, or am I getting mostly feathers?

Specialist subreddits including r/Bedding are blunt: at sub-$100 you are almost always buying a feather-down blend, not a true down comforter. Inserts like the APSMILE and several budget Amazon options are honest about being feather-forward, which is fine for value but means less loft and more weight than a premium all-down insert.
