Italian tradition and craftsmanship

DaunenStep down jackets are the result of Italian down-processing tradition : each piece is constructed and quilted by hand by expert craftsmen. The tailored finishes guarantee durability, precision, and a quality immediately perceptible to the touch.

Supersoft Batista lining: finesse and breathability

The 100% Supersoft Batista cotton fabric is gentle on the skin, soft, and deeply breathable. Certified anti-mite and completely hypoallergenic , it offers a dry microclimate even for those with dust allergies.

100% 730 CUIN down padding

The D400 uses a selection of 100% virgin down with a fill power of 730 CUIN , guaranteeing:

• enveloping softness
• optimal thermal insulation
• extreme lightness
• constant transpiration

Ethics and safety of production

The feathers are not sourced from live or abused animals. The duvet is suitable for allergy sufferers and is produced without harmful substances, in full compliance with OEKO-TEX standards.

4 Seasons System: three duvets in one

The modular structure allows you to use:

• Lightweight down jacket for summer and mid-season
• Mid-season down jacket for autumn and spring
• Both combined for complete winter warmth

Room temperature: how to choose the right heat level

Ideal comfort depends on the temperature of your room:

• 20–24°C: light down jacket
• 18–20°C: mid-season down jacket
• Below 18°C: combined use

Personal sensitivity to heat

If you're sensitive to the cold , choose the solid set; if you're a warm person , choose the mid-season set alone. A natural duvet guarantees comfort even with the window ajar thanks to its high hygroscopicity .

Fixed square quilting and buttonhole edge

The fixed square quilting keeps the down evenly distributed, preventing cold spots. The flat edge with buttonholes allows the two duvets to be easily joined.

Maintenance and durability

A quality duvet like the D400 will last for many years with proper care.

Washing instructions

• Washing: up to 40°C
• Dryer: recommended to maintain volume
• Full wash: every 3 years
