Layering Up: The Quick Guide to Mountain Cold

Anyone who spends time outdoors in the cold knows a single thick layer rarely gets the job done. The secret is layering pieces that work together, each with a specific role.

First layer (base): stays in contact with the skin and pulls sweat away from the body. Choose synthetic fabrics or merino wool, and avoid cotton, which traps moisture and cools the body quickly.

Second layer (insulation): responsible for retaining heat. Fleeces and puffer-style padded jackets belong here. The goal is to trap warm air close to the body.

Third layer (protection): a windbreaker or waterproof jacket that blocks wind, rain and snow without trapping sweat inside.

The great benefit of layering is flexibility: as temperature or physical effort changes throughout the day, you add or remove a layer instead of being too cold or too hot in a single piece. That's exactly why 3-in-1 jackets make so much sense: they already deliver two of these layers combined into one piece, ready to adapt to your day.
