How to layer: How to dress so you don't freeze or boil

Whether you're in the mountains or in the city, details often make the difference when it comes to dressing. And the most important detail is the right layering system. Thanks to it, you won't sweat, freeze or deal with the drama of thermal wrap. The key is the combination of the first layer, the insulating and protective layers that work together.

1. Base layer - Marylu Milk Skin

2. Insulation layer

You build insulation on the foundation. Here you can combine:
merino wool for natural thermoregulation,
down jackets with fill power 650+ for maximum weight-to-warmth ratio,
hemp or fleece for breathability and quick drying.

Tip : always check the density, weight or filling parameters. That way you know what you are really getting.

3. Protective layer

The last layer is a barrier against snow, rain and wind. Here it is important to monitor the technical parameters:
Water column: minimum 10–15,000 mm in the mountains, 20,000 mm in extreme conditions.
Breathability: 10,000 g/m²/24h and more.
Seams and zippers: always taped.

Materials like Sympatex, eVent or Pertex Shield ensure that your protection lasts even in harsh conditions.

What to look out for when choosing

Read the labels: if the name says "merino", check what percentage of it is actually there.
Cotton does not belong in the base layer: it retains sweat and makes you cold.
Don't get caught up in marketing, always look for realistic parameters.
