Our guarantee: we repair your gear for life

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

Who did we design it for?

For mountaineers who tackle long days out in extreme cold at high altitude.

At exposed belays, in bivvy or during glacial transitions, body heat dissipates within seconds.

These are practitioners for whom thermal reliability in extreme conditions is non-negotiable.

How should you wear it?

As an outer layer in cold and dry conditions, or as a mid layer under a waterproof jacket (hardshell) to tackle rain and snow.

To be worn over a thermal base layer to maximise heat retention at altitude.

Cut designed for insulation. This model runs large — we recommend the size down for optimal heat retention.

What makes the difference?

Its high-performance 800cuin natural down: that pack away at the bottom of your bag, yet insulate instantly the moment you put them on. The benchmark thermal protection for mountaineering and extreme cold expeditions.

Developed and tested by TEAM CIMALP athletes.

Maximum insulation for expedition

In the high mountains, cold sets in at the first stop. At the belay, in the bivvy or when the wind picks up at altitude, body heat drops sharply. Every minute without insulation costs energy — and sometimes far more.

This down jacket was designed to meet a single demand: instant protection from extreme cold, without ever weighing on your commitment. It traps heat from the very first seconds. Ultra-packable, it disappears to the bottom of the summit bag between pitches. Its cut follows technical movements without ever restricting mobility.

Because on expedition, warmth is a resource not to be wasted. The assurance of reliable insulation, from the refuge to the summit.

Key features

    Helmet-compatible hood

    The hood is compatible with a mountaineering helmet.

    Central zip with double sliders

    The central zip has two sliders. This means you can belay your climbing partner without opening your jacket fully.

    Harness-compatible pockets

    The pockets have been positioned so they remain accessible even when wearing a harness.

    Adjusters

    Reliable adjustment systems to dial in the perfect fit on your down jacket.

    Chest pocket

    Chest pocket to keep essential items within easy reach.

CIMACUIN Technology

Natural insulation delivering excellent thermal output in cold conditions.

  • High fill power (cuin) : natural down creating insulating air pockets to effectively retain body heat.
  • Very high compressibility : compacts tightly to reduce the garment's volume and make storage easier.
  • Exceptional warmth-to-weight ratio: delivers optimal insulation while maintaining great lightweight performance.

CIMACUIN technology is built around down selected for its quality and durability, delivering reliable thermal performance over time.
