How to stay warm and dry during my cross-country skiing outings?

We recommend the 3-layer technique.
Layer 1: second skin (technical base layer) wicks away moisture from the body to keep your skin dry.
Layer 2: insulating (t-shirt, fleece) layer that provides warmth and wicks away moisture outwards.
Layer 3: outer protective (jacket) layer that protects from the weather conditions: wind, snow and cold.

Adjust the number of layers to the level of your physical effort and the weather, and make sure that the clothing is breathable.
