Review: great duvet cover to keep them down feather INside. - good quality and this duvet holds the down feather iINSIDE! should have bought this sooner, made my life so much easier not having to vacuum the room every day cause I could see the white down feather everywhere. I used this duvet underneath my hotel collection duvet. Review: Keeps the down feathers in!! - Down is hands down the best temperature regulating material. But almost not worth it because of the escaping down! They are just a headache and mess!!! This solved that problem! I now can love my down comforters. It does not interfere with breathability. It is "loud" in that it crinkles. But this doesn't bother me. It sounds "crisp" to me. This is my second one. The first, I've washed multiple times. Just gets softer and holds up well. It feels like quality materials. Zipper is fantastic! And fits great. I haven't needed to test if it's water proof. I'd say just being dense enough to keep down inside it would be naturally water resistant. It is NOT plastic. Which some water proof materials are and they don't breathe. ## Features - 100% Cotton - Made in the USA or Imported - Advanced Protection: National Allergy Duvet Covers are made from 100% breathable cotton, which promotes a sounder nights rest.
