How Warm Is a Silk Duvet? A Fill Weight Guide by Climate
Quick answer: a silk duvet's warmth comes from its fill weight, the grams of silk inside, matched to how warm your bedroom is. For a Queen, about 700–750 g of silk suits rooms above 24°C (75°F) and hot sleepers. About 1,000–1,250 g suits mild climates like Los Angeles. About 1,500–1,750 g suits heated homes kept at 19–24°C (66–75°F), which is most of Canada and the northern US in winter.

How to choose
- What temperature is your bedroom at night? Above 24°C, choose Summer. Around 19–24°C with the heat on, choose the Canada Edition. Mild winters without much heating, choose the L.A. Edition.
- Do you sleep hot? Go one step lighter than your climate suggests.
- Do you sleep cold, or keep the bedroom below 19°C? Choose the Canada Edition and add a blanket on the coldest nights.
How a silk duvet feels compared with down
Down traps a lot of air, so it's lofty and very warm for its weight. Silk lies flatter and closer to the body. It breathes well and wicks moisture, so it tends to feel warm without the stuffy, sweaty feeling some people get under down. That's why silk is a popular choice for hot sleepers and for heated homes where down can feel like too much.
FAQ
Is a silk duvet warm enough for a Canadian winter?
Yes, in a heated home. Our Canada Edition is weighted for bedrooms kept at 19–24°C (66–75°F). If you keep your bedroom cooler than that, layer a blanket on top.
Is a heavier silk duvet better quality?
No. Fill weight decides warmth, not quality. Quality depends on the type of silk: look for 100% long-strand mulberry silk. See how to tell a real long-strand silk duvet.
Can I use one silk duvet all year?
In a home with heating and air conditioning, the Canada Edition works for most of the year. If your summers are hot or you sleep without AC, a separate Summer Duvet keeps you more comfortable.
Does a silk duvet go flat over time?
Long-strand silk is stretched into one continuous layer and held in place with stitching, so it keeps its shape. Short-strand silk is more likely to clump and shift.
