We Help Brands Own the Natural Cooling Blanket Category. Lyocell Shell + 100% Silk Fill — Two Premium Natural Fibers. One Cooling Blanket. OEKO-TEX Certified.
What Is a Lyocell-Shell Silk-Filled Cooling Blanket?
A lyocell-shell silk-filled cooling blanket is a premium lightweight blanket combining two natural fibers for all-night cooling performance. The outer shell is lyocell — a plant-derived fiber that provides naturally smooth, cool-touch skin contact and actively wicks moisture away from the body. The fill is 100% silk — natural silk fiber has a porous structure that allows continuous airflow and natural thermal self-regulation. Sewn-through construction keeps the silk fill evenly distributed across the full blanket surface. The entire construction is certified OEKO-TEX Standard 100 and SGS tested.

Q1. What is a lyocell-shell silk-filled cooling blanket? A lyocell-shell silk-filled cooling blanket combines two natural fibers for all-night cooling performance. The outer shell is lyocell — a plant-derived fiber with a smooth surface that actively wicks moisture away from the skin, providing sustained cool-touch throughout the night. The fill is 100% silk — natural silk fiber has a porous structure that allows air to circulate, providing breathable warmth and natural thermal self-regulation. The combination addresses the two main cooling failure points: a surface that stays cool all night, and a fill that does not trap heat.
Q2. How is this different from a standard synthetic cooling blanket? Synthetic cooling blankets (polyester or nylon) provide an initial cool-touch sensation at first contact, but the synthetic fill beneath retains heat as body temperature rises — the cooling effect is temporary. This blanket uses lyocell — a plant-derived fiber with natural moisture-wicking properties — which sustains cooling by actively moving moisture away from the skin rather than only providing initial surface cooling. The 100% silk fill adds breathable natural thermal self-regulation that synthetic fills do not have.
Q3. Is this blanket suitable for hot sleepers? Yes — this blanket is specifically designed for hot sleepers. The lyocell outer surface actively wicks moisture and maintains a cool-touch feel through breathable natural fiber properties. The 100% silk fill has a porous structure that allows continuous airflow rather than trapping heat. Users report sleeping through warm summer nights comfortably. However, it is a lightweight natural blanket, not a cooling device — it performs best in warm to moderate sleeping environments.
Q4. What does OEKO-TEX Standard 100 certification mean for this blanket? OEKO-TEX Standard 100 certification means the entire blanket — outer shell fabric, 100% silk fill, stitching thread, and dyes — has been independently tested and confirmed free from harmful substances. This is a full-construction certification, not just a material certification. It covers every component of the final product. SGS testing provides additional product-level quality verification across production batches. Together they provide verifiable natural fiber credentials for brands positioning in premium, wellness, or clean bedding segments.
Q5. What is lyocell and how is it different from cotton? Lyocell is a plant-derived cellulose fiber produced from wood pulp. It has a naturally smooth surface with a moisture-wicking fiber structure that draws moisture away from the skin more efficiently than cotton. Cotton breathes well but absorbs moisture into the fiber — lyocell moves moisture away from the skin surface. This makes lyocell more effective as a cooling surface layer in a blanket. Lyocell is also softer, has a natural sheen, and is naturally anti-static — it does not create hair friction or static charge.
Q6. How does the silk fill provide thermal self-regulation? Natural silk fiber has a triangular porous cross-section that allows air to flow through the fill layer. This provides breathable warmth: in warm conditions, air circulation prevents heat buildup; in cooler conditions, the fill insulates. Polyester fill has a solid fiber structure that traps heat consistently — it does not self-regulate. Silk's natural self-regulation is why this blanket performs across all seasons — it is not limited to summer use.
Q7. What sizes are available? Queen: 87×90 inches. King: 102×90 inches. Custom dimensions are also available for OEM orders. Colors: Light Blue, Pearl White, Grey.
Q8. How do I care for this blanket? Professional dry cleaning is recommended to maintain the silk fill and lyocell shell in optimal condition. If machine washing is preferred: machine wash cold on a delicate cycle with a mild detergent suitable for delicate fabrics. Do not bleach. Do not tumble dry. Lay flat to dry away from direct sunlight. Store in a cool, dry place when not in use.
Q9. Can this blanket be used year-round? Yes — the 100% silk fill provides natural thermal self-regulation, adjusting to body and ambient temperature. The blanket is lightweight and thin, making it suitable for warm seasons as a primary sleep layer, and for cooler seasons as a layering piece under a heavier comforter. It is not a heavy winter comforter — it is positioned as an all-season premium natural cooling layer.
Q10. Can this be customized for my brand? Yes. EastWest Sleep manufactures lyocell-shell silk-filled cooling blankets for OEM and ODM customization. Options include shell fabric selection, silk fill weight, sewn-through grid pattern, size (Queen / King / custom dimensions), color, label, and packaging. OEKO-TEX Standard 100 and SGS certification can be maintained across OEM production batches. EastWest Sleep has developed 300+ premium bedding products for brands across 40+ countries.
