OUTLAST Duvet – intelligent sleep comfort all night long
The OUTLAST duvet is a modern answer to the problem of overheating and chilling during sleep. Thanks to the technology originally used by NASA, this thermoactive duvet actively reacts to your body temperature. This means it provides pleasant coolness when it's too warm, and releases warmth when it gets cooler – creating ideal conditions for regeneration every night.
Outlast Technology – dynamic temperature regulation
The Outlast duvet contains microcapsules with natural wax that store excess heat and release it when needed. This solution helps maintain a stable sleep microclimate.
The result is a peaceful, uninterrupted sleep without sudden temperature changes.
Comfort without overheating
The cooling duvet reduces sweating by absorbing excess heat. Thanks to this, even on warmer nights, sleep remains comfortable.
This is an ideal solution for people sensitive to temperature.
Warmth when you need it
The all-season duvet releases stored heat when the temperature drops. Thanks to this, you don't feel cold at night.
Thermal comfort is maintained throughout sleep.
Two-sided functionality
The reversible duvet combines a cooling Outlast side with a warm, soft cotton sateen side. You can adapt the side to your preferences.
This is convenience and flexibility in one product.

- summer – a lightweight version for warm nights and heated bedrooms
