Temperature regulating

Wool is known for its warmth, but what not many people know is that wool is also very often used as insulation against heat! For example, Bedouins in Sinai wear woolen robes to protect themselves from the extreme desert heat. Wool keeps you warm when you are cold and cool, when you are hot. Wool fabrics insulate better than most other textiles, thus transmitting less heat or cold. You can wear wool in severe cold or in extreme heat and still feel comfortable.
