Yes. Wool bedding actively regulates your body temperature by absorbing up to 35% of its weight in moisture vapour and releasing heat through evaporation - a cycle that polyester, down, and cotton cannot replicate. A 2026 Bangor University study found wool duvets transmitted up to 139% more moisture than synthetic alternatives at elevated temperatures, while maintaining 22°C at the duvet centre overnight compared to just 13–15°C for other materials. Wisewool™ uses New Zealand strong wool, which has thicker fibres and greater natural crimp than merino, creating superior airflow in bedding and mattress applications.
