A duvet for all seasons

• Lightweight down jacket for summer and spring
• Mid-season down jacket ideal for autumn
• Combined for complete winter warmth

Supersoft Batista lining: softness and breathability

The 100% cotton Supersoft Batiste fabric is extremely fine, silky, and durable. Completely hypoallergenic and certified anti-mite, it ensures high breathability and a dry microclimate in all seasons.

100% 730 CUIN down padding

The D400 uses exclusively 100% virgin down with a fill power of 730 CUIN , a value that guarantees:

• softness and natural volume
• excellent thermal insulation
• extreme lightness
• continuous thermoregulation during the night

Fixed square quilting: uniform heat

The fixed square quilting keeps the down evenly distributed, preventing cold spots. The flat edge with buttonholes allows you to join the two duvets in seconds.

Room temperature: how to adjust its use

Choose the right combination based on the temperature:

• 20–24°C: light down jacket
• 18–20°C: mid-season down jacket
• Below 18°C: Both combined for winter warmth

Personal sensitivity to heat

Perception is subjective: those who feel the cold will prefer the warmest combination, while those who prefer warmth will find just the mid-season combination sufficient. Natural down guarantees comfort even with the window ajar thanks to its high hygroscopicity .

• much higher breathability
• natural thermoregulation
