Yes, wool blankets are known to be warm. Wool is a natural insulator, which means that it helps to trap heat and keep you warm.
The structure of wool fibers makes it difficult for heat to escape, so wool blankets can keep you warm even on cold nights. Additionally, wool is naturally moisture-wicking, which helps to regulate body temperature and keep you comfortable. Wool blankets are often made from Merino wool, known for their softness and warmth.
Merino wool fibers are finer than traditional ones, making them more comfortable against the skin. Some wool blankets are also blended with other materials like cotton or synthetic fibers, adding to the blanket's softness and durability while still providing warmth. Overall, wool blankets are an excellent option for those who want a warm and cozy blanket that will keep them comfortable throughout the night.
