Who did we design it for?

For mountaineers and skiers heading out on hiking trips who want an ultralight layer for extra warmth that fits into a summit pack.

How warm is it?

Extra warmth: 800 cuin natural down keeps you warm at belay stations, during a bivvy and when stopping on snow. In very cold conditions, add a warm layer underneath.

How much does it weigh, and how small does it pack?

300 g in size M. Highly compressible, it packs down to fit in your hand and takes up very little room in a summit pack.

What makes it different?

Our CIMACUIN technology: RDS-certified, 800 cuin natural down that packs down into the bottom of your rucksack and insulates as soon as you put it on. An excellent warmth-to-weight ratio.

Hiking

Not a gram to spare

At the start of a climb or a ski touring trip, anything you don’t need weighs you down. We needed an emergency layer that wouldn’t take up room needed for other kit in your summit pack.

This down jacket packs down small enough to fit in your hand and takes up next to no space. Its natural down delivers immediate warmth when you pull it on at a belay; its helmet-compatible hood and pockets accessible under a harness are designed for technical climbing.

Its water-repellent treatment sheds light snow, whether you’re at a belay or on a bivvy.

Because an emergency layer is only useful if it’s in your pack when you need it.

Key features

Helmet-compatible hood

The hood is compatible with wearing a mountaineering helmet.

Harness-compatible pockets

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

Chest pocket

Chest pocket to keep essential items within reach.

Minimalist

This down jacket will keep you warm without taking up space in your pack.

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.

In summary This content is written by AI

Customers are won over by its light weight and compactness: most find it ultra-light, while several appreciate being able to pack it into its pocket or small bag, down to roughly the size of two fists. They also praise its effective warmth, both in the mountains and during active winter use, as well as its comfortable fit, close to the body while still allowing room to move. Several wear it for hiking, mountaineering or paragliding, sometimes as a fourth layer. One customer even uses it instead of a fleece to lighten their pack.

Great down jacket. Once folded into its small bag, it takes up about the volume of two fists. Warm, nice to look at and wear. Ultra light. It replaces my fleece to lighten my pack.

Really light and compressible. Used actively in the winter and statically in the summer. I don't have enough perspective yet, but the level of warmth provided seems to correspond to this program. For an alpine-oriented jacket, one could almost expect a double zipper (the existing one works very well with one hand) for use with a harness.

Paragliding isn't listed as a primary activity, yet that's its main use for it, due to its lightness and compressibility (in my case). Then come other mountain activities like hiking, mountaineering, etc. A very nice product and very well designed!

Used in the mountains as a 4th layer, it delivers the minimum weight/warmth/bulk ratio.

Wash this jacket with 800 cuin natural down as infrequently as possible, in cold water with a liquid detergent designed for down and no fabric softener. Tumble-dry on a gentle cycle with tennis balls, shaking and patting it every 20 minutes, or dry it flat in the open air. If the feathers clump together, pour a down waterproofer into the fabric-softener compartment before the second rinse.
