Wool is the most common material used in men's suits. It is a natural fiber that is completely different from other materials. The structure of its fiber is curly, giving clothes excellent insulator qualities: it warms in the cold, and breathes well in the warm. Wool fabric binds air providing an insulating layer. At the same time, wool effectively removes humidity away from the skin, so it does not feel clammy or stuffy. Thanks to its antibacterial properties, wool repels odors maintaining fresh sensation longer. At the same time, it is environmentally friendly, as the need for washing is few.

Because of its curly fiber, wool is naturally flexible and returns well to its original shape. For this reason, suits and coats, among other garments, maintain their prestige and look neat even after a long day. This property takes wool particularly useful for clothing in
occasions to make an impact. It also repels dirt and odors. The scale-surfaced fiber structure prevents impurities from being absorbed deep into the fabric. It is often enough to give some air a wool garment outside to freshen it up without washing it. This makes wool a fairly easy-care material.
