Filling
100% 6A grade long-strand Mulberry silk, hand-stretched layer by layer for an even structure, with lasting lightness and enduring softness.
Shell
Made from 300 thread count high-density Cotton in White, offering a soft and comfortable touch, excellent breathability, and long-lasting durability to protect the silk filling.
Weight & Warmth
150 GSM (silk filling weight per square meter), providing an insulation level roughly equivalent to 2–4 Tog. Designed for summer use and warm climates. For detailed filling weights and warmth levels by size, please refer to the chart on this page.
Craftsmanship & Care
The filling and shell are secured with fine quilting, ensuring the silk layers remain stable and evenly distributed. Pair with a silk duvet cover to maintain cleanliness and extend its lifespan. Custom sizes silk duvets are available to suit individual needs.
About GSM & Tog
GSM (grams per square meter) measures the weight of the duvet filling - the higher the GSM, the warmer the duvet. Tog is another unit for warmth, representing how well the duvet insulates and retains heat.
Quick Reference:
• 150 GSM ≈ 2-4 Tog (Summer use)
• 250 GSM ≈ 4-6 Tog (All season, lightweight)
• 300 GSM ≈ 7-9 Tog (All season, medium warmth)
• 400 GSM ≈ 9-11 Tog (Winter, extra warm)
