How to stay warm on a mountain hike

Whether your mountain hikes are short or long, one thing is for sure: good experiences come with good planning. Most people have learned from experience about the unpredictable weather; even a glorious summer day can quickly turn cold.


Wool for all types of hikes

For Norwegians, the Mountain code is embedded from an early age, but just as important is the multi-layer principle. Wether your destination is Norway or somewhere else, knowing both will help you on your next hike —especially the last one.

In short, the multi-layer principle means putting on layes depening on the trip, activity and weather conditions. The baselayer should be close-fitting, this is to transport moisture from your body while keeping you warm and dry. The mid layer is for insulation and temperature regulation, and is a little looser than the first layer. The mid-layer can easily be taken off or on depening on the intensity and weather. The cover layer protects from snow, wind and rain. 
Ulvang offers a wide range of clothing for base- and mid layers, for all activites and weather conditions.
