Not sure which duvet fits? We've design a quiz to help! 

Filled with double-cocoon mulberry silk, the top grade of silk, and handmade by four skilled artisans for each piece, this mulberry silk-filled duvet insert stands as a beacon of luxury. With the inherent characteristics of silk, the duvet insert is supremely soft, smooth, and excels in temperature regulation.


  • Fill: 100% double cocoon long-strand mulberry silk (also known as dupioni or 7A) - the most premium grade of silk
  • Shell: Luxe Long-Staple Cotton with a 330 thread count and a sateen weave. Buttery smooth and extra soft  
  • Differs from the Mulberry Silk-filled Duvet Insert with Organic Cotton Shell only in the shell material. A Luxe Long-Staple Cotton Shell offers a softer and silkier texture, while an Organic Cotton Shell provides a crisper and more sustainable alternative
  • Tack stitch to enhance fill stability while preserving the duvet's smooth and fluffy texture
  • Three loops on each side of the insert for securing with a duvet cover
  • Handmade by skilled artisans with decades of experience, each fill is hand-stretched from silk cocoons and professionally layered to ensure a smooth and even distribution
  • Shell and fill both surpass the strictest Class I OEKO-TEX® Standard 100 certification, tested and proven free of harmful chemicals
  • Strongly recommended for use with a duvet cover
  • Sun-curing recommended for daily maintenance 
  • Professional dry clean
  • Spot clean if necessary

Incredibly Happy!!

I had never heard of this brand or Millbury silk duvet insert, so is taking a chance here. I’ve used down alternative because I tend to sleep hot and wind up sweating. I’ve been using it now for two weeks and have had the best nights sleep I’ve had in a while. It feels so luxurious you and I love how it doesn’t clump. Very impressed with the quality and how beautifully it came packaged.

Best ever

I honestly think Aeptom makes the best silk duvets. I bought the organic cotton one a few years ago and absolutely loved it. This year, I wanted something a little lighter but wasn’t sure which shell option to choose (they didn't have these options before). Customer support was amazing. They explained the differences clearly and didn’t try to push me into anything, which I really appreciated. I ended up going with the luxe cotton version in lightweight, and it’s even better than I expected. It’s so soft and fluffy, and I think I like it even more than the organic cotton one. Will definitely be ordering more!
