For the mountaineers who commit to long outings in extreme cold at high altitude.

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

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

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

Wear over a base layer to maximise heat retention at altitude.

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

Its high-performance natural 800cuin down : that disappear to the bottom of your pack, but 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.

Lifetime repair

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

Maximum insulation for expedition

At high altitude, the cold sets in the moment you stop. At a belay, in a bivouac, or when the wind picks up on the ridge, body heat drops fast. Every minute without insulation costs energy — and sometimes much more.

This down jacket was built around a single demand: instant protection against extreme cold, without ever weighing on your commitment. It traps heat within seconds. Ultra-compressible, it disappears to the bottom of your summit pack between pitches. Its cut moves with technical gestures without ever restricting mobility.

Because on expedition, warmth is a resource you can't afford to waste. Reliable insulation you can count on, from the refuge to the summit.

CIMACUIN Technology

Natural insulation offering excellent thermal output for cold conditions.

  • High fill power (cuin) : natural down creating insulating air pockets to efficiently retain body heat.
  • Extremely high compressibility : compacts down hard to reduce the volume of the garment and make storage easier.
  • Excellent warmth-to-weight ratio: delivers optimal insulation while keeping overall weight lightweight.

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

Key features

    Helmet-compatible hood

    The hood is compatible with wearing 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.
