This is just the beginning and the base layer is the foundation of the complete ensemble. People sometimes will become confused with how they are supposed to properly layer their clothes. When heading out to an adventure with unpredictable weather (or just flat out cold), layering your clothes correctly can be the difference in a great time or a miserable time. While not going too in-depth here, here is a general guide that you can take.
The base layer, which you now are fully educated on, will manage the moisture and provide the initial layer of insulation. This should go on first before anything else, then you can put on your second insulating layer. While this will vary, this could be a long-sleeve shirt or a sweatshirt. Lastly, you would want your outer shell on last to protect you against the rain and the wind. For example, a Gore-Tex jacket.
