A useful layering system manages moisture, warmth, and weather. It should be easy to adjust while moving.

Base layer

Choose a comfortable material that moves moisture away from the skin. Match its warmth to your activity level and temperature; more fabric is not always better when you are moving hard.

Insulation layer

Fleece or insulated jackets hold warm air. Carry enough insulation for stops, wind, and an unexpected delay—not only for the temperature while walking.

Weather layer

A shell protects against wind and precipitation. Ventilation and fit matter because trapped moisture can make you cold later.

FAQ

Should I wear every layer from the start?

Usually not. Start slightly cool and add insulation during stops. Adjust early, before sweat soaks the base layer.
