When outdoors, layering is smart way to manage body heat. This tried-and-true strategy lets you regulate comfort by slipping layers on and off as your activity level or the weather changes.

How to layer: To understand layering your clothing for outdoor activities, you need to know the function of each layer:

1. Base layer : wicks sweat off your skin

2. Middle layer (insulating layer): retains body heat to protect you from the cold

3. Outer layer (shell layer): shields you from elements such as wind and rain
