Layering outdoor clothing is essential to keep one's body warm while remaining comfortable despite the ever-changing weather conditions.
Here are four principles in layering that will keep you warm and comfy:

1. Base layer - A moisture-wicking fabric must be worn by the person directly as it preserves one's body temperature. Merino wool or synthetic material are excellent options to use as a base layer.

2. Insulating layer - The purpose of insulating layers is to trap the air close to the body. As a result, it gives warmth to the body. Synthetic insulated jackets, fleece, or wool sweaters can be used as an insulating layer.

3. Shell layer - The purpose of this layer is to protect the self from rain and wind. For example, try wearing a waterproof and lightweight jacket, such as a Gore-Tex jacket, which can serve as your shell layer.

4. Accessory layers - Do not forget to try adding accessories like neck warmers, gloves, or hats, since it provides you additional warmth and protection when going outdoors.

The intensity of activities you will be doing and the weather conditions are vital factors you should consider when layering clothing. When you engage in more strenuous activities, opt for lighter pieces of layers to allow better ventilation. In contrast, adding more layers is essential in keeping yourself warm when the temperature is low.

It is also important to remember to wear clothing that fits perfectly on you so that you can freely move without any difficulty. In addition, it will also allow you to adjust layers whenever you still need to do some adjusting. Layering is done to regulate a person's body temperature to make a person feel comfortable despite being outdoors. No matter what adventure it is, proper layering will help you weather the storm and challenges you might encounter.
