Wool is an excellent natural insulator. It helps regulate body temperature by trapping heat in cold weather and releasing it when it's warm. Wool fibers have natural moisture-wicking properties, allowing them to absorb moisture. Wool is also resistant to dust mites, mold, and mildew, making it an ideal choice for allergy sufferers. It's also naturally antimicrobial, inhibiting the growth of bacteria that can cause allergies. Wool is a renewable and biodegradable material, making wool duvets an eco-friendly choice.Available in four sizes, Twin 66 x 88'', Double 80 x 88'', Queen 90 x 88'', King 104 x 88''.
