Frequently Asked Questions
What is Kosmu Silk-filled Duvet made of?

What’s the difference between natural silk and mulberry silk.
Natural silk, also known as wild silk, is harvested from silkworms that live in their natural environment, feeding on a diverse range of leaves such as oak and castor. This type of silk has a coarser texture and a more irregular, natural appearance. Despite this, it remains luxuriously soft, with thermoregulating properties, making it a great option for those new to silk or seeking a more affordable choice.
Mulberry silk, on the other hand, is unique because the silkworms are domesticated and fed exclusively on mulberry leaves. This specialized diet produces silk that is pure white, exceptionally soft, and smooth. Known for its consistent, fine texture and natural sheen, mulberry silk is also stronger and more uniform than wild silk. It's ideal for those who appreciate the value of silk for better sleep and seek a nearly lifelong sleep companion.
Can I use Kosmu Silk-filled Duvet year round?
Absolutely! Silk is naturally thermoregulating, which means it keeps you warm in the winter by trapping heat, while also being breathable and cool in the summer, allowing excess heat to escape. This makes it an ideal choice for maintaining comfort in all seasons. Plus, silk's lightweight feel adds to the overall year-round versatility of the Kosmu Silk-filled Duvet.
