    Why Long-Strand Silk Matters

    Uniform Warmth without Clumping

    • Long-Strand: Fibers extend across the entire duvet, staying in place for a lifetime.
    • Short-Strand: Fibers shift and bunch up after a few uses, creating cold spots.

    Unparalleled Durability

    • Long-Strand: High tensile strength; resists breaking even after years of use.
    • Short-Strand: Brittle and fragile; loses loft and "cloud-like" feel quickly.

    Superior Breathability

    • Long-Strand: Layered by hand to create millions of tiny air pockets.
    • Short-Strand: Dense and compressed, trapping heat rather than regulating it.
    100% Hand-Layering Craftsmanship

    Each comforter is layered by hand in a cross-grid pattern. This traditional technique creates thousands of tiny air pockets for maximum loft and thermal regulation.

    Naturally Hypoallergenic

    Rich in sericin protein, silk naturally repels dust mites, mold, and bacteria, creating a pure and safe sanctuary for sensitive skin.

    Invisible Inspection Zip

    Features a long side zipper, allowing you to touch and verify the premium 6A long-strand silk quality yourself.

    Exquisite Box Stitching

    Delicate handcrafted stitching keeps the filling evenly distributed while maintaining maximum breathability.

    Silk Comforter Wisdom: Your Questions Answered

    How do I choose the right weight for my climate?

    We offer three weights: Summer (above 22°C/72°F), All-Season (15-22°C/59-72°F), and Winter (below 15°C/59°F). If you use AC year-round, All-Season is our most versatile recommendation.

    Does the silk filling shift or clump over time?

    No. Unlike short-fiber silk or down, THXSILK uses premium long-strand silk. We use a traditional hand-layering technique and precision stitching to ensure the filling stays perfectly even for decades.

    Why does my new silk comforter have a faint scent?

    A slight, natural "earthy" scent is a hallmark of 100% pure, untreated mulberry silk (from the sericin protein). This is not a chemical smell and will naturally dissipate after airing out for 24-48 hours.

    Is a silk comforter really better for allergy sufferers?

    Absolutely. Silk is naturally hypoallergenic and contains sericin, which repels dust mites, mold, and bacteria. It is the safest choice for sensitive skin and respiratory systems.

    Can I machine wash the entire comforter?

    We strongly advise against washing the silk core. To preserve its loft, always use a duvet cover and wash the cover only. For the comforter, simply air it in a shaded area periodically to refresh the fibers.
