How a 4-season duvet works

The duvet is made up of:

• a lightweight down jacket for spring and summer
• a mid-season down jacket for autumn and mid-seasons
• united together: ideal winter warmth even in cold rooms

Batista Supersoft lining: superior softness

The D400 is covered in 100% Supersoft Batista cotton , a very fine, light, silky-touch, and completely hypoallergenic fabric. Thanks to its high breathability, it ensures a dry and comfortable microclimate in every season.

100% 730 CUIN down padding

The D400 duvet filling is made with 100% virgin down , featuring a fill power of 730 CUIN . This value guarantees:

• high softness and natural volume
• balanced and comfortable warmth
• great thermoregulating capacity
• lightness and well-being at night

Fixed square quilting: no cold spots

The fixed square quilting keeps the down evenly distributed and prevents the filling from shifting, ensuring consistent comfort. The flat edge with buttonholes allows the two duvets to be joined together conveniently and securely.

Room temperature: choose the perfect level of heat

To choose the ideal combination, consider the temperature of your room:

• 20–24°C : use a light duvet
• 18–20°C : use mid-season
• Below 18°C : Use both for maximum heat

Personal thermal sensitivity matters

If you're sensitive to the cold, choose a warmer combination; if you're a warmer person , choose a lightweight or mid-season version. Natural down always provides a dry microclimate even with the window slightly open, thanks to its hygroscopicity .

Why choose an original natural duvet

Compared to synthetics, a goose down duvet offers:

• superior breathability
• dry microclimate all night
• natural thermoregulation
• significantly longer lifespan

Easy maintenance and long life

The D400 down jacket is designed to maintain performance and volume over time.
