For winter hikers and mountaineers who face extreme cold in the mountains, from glacial routes to winter expeditions.

They alternate between sustained effort and exposed rest stops in the wind, where thermal management determines performance level.

This profile demands a base layer capable of keep the body warm even when effort pauses.

Wear as a base layer directly on the skin to optimise moisture transfer. Layer a thermal fleece in extreme cold, and a hardshell jacket in wind or rain. Second-skin fitted cut — your usual size.

Its double insulating construction at 285g delivers the level of warmth that extreme high-mountain conditions demand, without ever blocking active moisture evacuation. A thermal balance maintained from the ascent to the bivvy.

Lifetime repair

A repaired garment is a story extended. We ensure the longevity of your Cimalp equipment, season after season.

Insulation that withstands extreme cold

In high mountain conditions, temperatures drop below zero before you even set off. An inadequate base layer turns every rest stop into an ordeal: cold seeps in, moisture lingers, effort becomes risk.

This base layer was designed for the most hostile conditions. Its dual insulation captures and retains body heat while actively transferring moisture to the outside. It neutralises odours over time, maintaining stable thermal comfort from the ascent to the bivouac.

Because extreme cold makes no compromises. Neither should your base layer.
