For winter wear, many people choose to wear only one jacket, while others alternate between multiple jackets. To make this decision, consider your needs and the temperature. For example, if you are engaging in a high-impact sport such as cross-country skiing at -20°C, a thin windbreaker would probably suffice. However, if you are walking around town at night and intend to experience more moderate temperatures (-10°C), then you might prefer a thick and warm jacket.
