Running in freezing conditions is something that runners in the North are very familiar with. With a long winter and a short summer, it becomes important to be able to train in any kind of weather. Therefore, layering correctly for the cold is an art of balancing the right amount and types of technical layers.

It's generally recommended to wear fewer layers, made from synthetic materials, instead of many layers with natural materials such as cotton.

When preparing for a run in a below-freezing temperature (-10˚C / 14˚F), the first thing you want to make sure of is to wear a good base layer. The base layer is the foundation of layering, as a poor base-layer can render the most expensive outer layers useless, and its main role is to wick sweat away from your skin to help your body maintain its regular temperature. Recommended base-layers for -10˚C / 14˚F would be the Básar merino wool top, a zip neck or crewneck. The merino wool in the Básar base-layer is extremely efficient in generating warmth while you run as the fibers of the wool trap air, which helps to retain warmth. Using a single shell outer-layer can do the job for many, but some might want to wear an insulated outer-layer or an extra layer underneath their shell. Keep in mind that you need to factor in the intensity of your exercise when choosing your layers; more intensity, lighter layering.
