100% Silk Duvet Inner | 400gsm Winter Weight

Genuinely warm. Surprisingly light. Remarkably kind.

The 400gsm Winter Weight silk duvet inner delivers real warmth - the kind that wraps around you rather than sitting on top of you - without the weight or bulk of a down or wool duvet. Pure long-strand mulberry silk floss is one of nature's finest insulators, trapping warmth efficiently while remaining breathable enough that you never overheat.

Silk's exceptional temperature-regulating qualities make it particularly well suited to those whose sleep is disrupted by fluctuating body temperature. It responds to your body's needs through the night, helping you stay in that perfect zone of warmth without waking too hot.

Completely chemical-free and naturally hypoallergenic - resistant to dust mites and the allergens that build up in closed winter rooms - it's a meaningful upgrade for anyone who has struggled with allergies, asthma or skin sensitivity through the colder months.

• Fill weight: 400gsm of pure silk floss only - not combined with the cover weight
• Fill: 100% long-strand mulberry silk, no chemicals
• Naturally hypoallergenic - dust-mite and allergen resistant
• Temperature-regulating - warm without overheating, night after night
• Lightweight - the warmth of wool at a fraction of the weight
