4 Seasons System: three duvets in one

Thanks to the modular system you can use:

• Lightweight down jacket for summer and spring
• Mid-season down jacket for autumn
• Joined together for complete winter warmth

Room temperature and heat selection

Here's the guide to selecting the correct use:

• 20–24°C: light down jacket
• 18–20°C: mid-season down jacket
• Below 18°C: both together

Personal sensitivity to heat

If you're sensitive to the cold , use the warmest combination; if you're a warm person , just the mid-season is often enough. The natural hygroscopicity of down ensures comfort even with the window ajar.
