Filling
100% 6A grade long-strand Mulberry silk, hand-stretched layer by layer for a dense, even structure that remains light and soft over time.
Shell
Crafted from 22 momme Mulberry silk in undyed natural white, with a refined softness and elegant sheen that embody both purity and enduring luxury.
Weight & Warmth
400 GSM (silk filling weight per square meter), providing an insulation level roughly equivalent to 9-11 Tog. Designed for winter and cold 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 size silk duvets are available for a personalized fit.
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)
