Wearing wool means wearing its softness. When it is soft, it will contain more air and keep warm better.

Method of softening wool coat;

Method 1: Try not to wash with cold water. Cold water itself has a high hardness. Washing clothes with cold water will naturally leave some minerals with higher hardness in the clothes fibers. You can add some hot water to the cold water appropriately. This will ease it a little.

Method 2: A more effective method is to use a fabric softener, which is more important than any trick.

Method 3: After the clothes are dried, you can gently pat the coat with a wooden stick. It's like hitting the quilt after the sun. In this way, the substance left in the clothes that causes the clothes to harden will come out and will not be so hard.
