    What is Double-Cocoon Silk?

    Unlike traditional silk, which comes from a single silkworm cocoon, double-cocoon silk is formed when two silkworms spin one cocoon together. This creates naturally intertwined, irregular filaments that are shorter and thicker.

    The result? A duvet filling that is exceptionally plump, resilient, and durable. The interlocked fibres create more tiny air pockets, giving you superior warmth without extra weight—and because they're naturally tangled, the filling stays evenly distributed and won't clump or shift over time.

    What wraps you on cold nights matters.

    At first glance, it feels like our cozy cotton shell. But the true warmth lies within. While the cover is crafted from soft, breathable cotton for comfort against your skin, the inside is generously filled with premium double-cocoon silk—a natural insulator that most duvets don't offer. Unlike heavy synthetic layers that trap sweat, this silk core provides exceptional warmth without the weight, trapping just the right amount of heat while staying breathable. Ideal for winter nights and cold sleepers.

    How to Care for Your Silk Duvet?

    Use a Duvet Cover
    The best way to protect your silk duvet is to keep it inside a removable, washable duvet cover. This shields the natural silk filling from daily dirt, oils, and spills—meaning you'll need to wash the duvet itself far less often.

    Do Not Machine Wash
    Unlike synthetic or some cotton duvets, silk should not be machine washed. Water can damage the delicate silk fibres, causing them to become stiff, clump together, or lose their natural loft and warmth.

    Below, we answer the most common questions to help you.

    What exactly is this duvet made of?

    This duvet features a two-part natural construction:

    The Shell: Made from 100% breathable cotton, providing a soft, natural feel against your skin.

    The Filling: Filled with double-cocoon silk. Unlike traditional silk, which comes from a single silkworm cocoon, double-cocoon silk is formed when two silkworms spin one cocoon together. This creates naturally intertwined, irregular filaments that are shorter and thicker.

    What is Double-Cocoon Silk? And how is it different from other silk?

    The result? A duvet filling that is exceptionally plump, resilient, and durable. The interlocked fibres create more tiny air pockets, giving you superior warmth without extra weight—and because they're naturally tangled, the filling stays evenly distributed and won't clump or shift over time.

    I'm a hot sleeper. Is this a good choice for me?

    Yes, this duvet is perfect for hot sleepers. Silk is exceptionally breathable and moisture-wicking. The cotton shell adds to this breathability, helping to draw heat and moisture away from your body to keep you cool and dry throughout the night.

    The big question: Is this duvet REALLY machine washable?

    No, it isn't! The best way to protect your silk duvet is to keep it inside a removable, washable duvet cover. This shields the natural silk filling from daily dirt, oils, and spills—meaning you'll need to wash the duvet itself far less often.

    Is this duvet suitable for people with allergies?

    Yes, it is an excellent choice for allergy sufferers. Both the cotton shell and the Tussah silk filling are naturally hypoallergenic. Silk, in particular, is resistant to dust mites and mould, creating a healthier sleeping environment without the need for chemical treatments.

    Will this duvet keep me warm in winter and cool in summer?

    Absolutely. Silk, is a brilliant natural temperature regulator. It actively adapts to your body, trapping warm air when you're cold and wicking away moisture and excess heat when you're too warm. This makes it a true four-season duvet, providing year-round comfort.

    How long will this duvet last?

    With proper care, this duvet is built to last.

    Who is this duvet perfect for?

    This duvet is the ideal choice if you:

    • Want the luxurious, breathable comfort of natural silk.
    • Prefer an ethical and durable alternative to standard silk.
    • Need a duvet that is easy to care for and machine washable.
    • Suffer from allergies and want a naturally hypoallergenic sleep surface.
    • Are a hot sleeper looking for excellent temperature regulation
    Do these duvets have a distinctive smell?

    Silk: Some people notice a very faint, unique odour when a silk duvet is new. This is due to sericin, a natural protein found in silk. It is not a chemical smell and usually fades within a couple of weeks of airing
