The Duvet is as healthy and free of toxin material as you can get anywhere.
The natural antibacterial properties of wool, along with its inherent ability to regulate both temperature and moisture, creates the best possible conditions for a healthy natural nights sleep. No chemicals, no fire retardants, no man-made fibres. Just perfect!
Wool duvets are sold by the gram weight of wool per square metre and are warmer than equivalent polyester or feather tog rating gram for gram. And therefore a lighter weight can be used.
