Should I wear a down jacket in winter in Los Angeles?

**Not required**. The winter in Los Angeles is not cold. The general temperature is between 10-18 degrees. The sun is shining and there are rarely rainy weather, so down jackets are not a necessity. It is recommended to prepare some spring and autumn clothes, such as thin sweaters, cashmere sweaters, thick jackets, coats, etc., to cope with the cold and unexpected weather changes in winter.
