Who did we design it for?

For women who go mountaineering and ski touring and 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?

250 g in size S. 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.

Warmth you forget is in your pack

On a ski touring trip, you feel every gram in your pack in your legs. In mountaineering, every extra layer restricts movement. We needed a down jacket that didn’t force a compromise.

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 stopping on the snow or at a bivvy.

Because the best layers are the ones you forget are in your pack until you need them.

Key features

Helmet-compatible hood

The hood is compatible with the wearing of a mountaineering helmet.

Harness-compatible pockets

Pockets are positioned to remain accessible even when wearing a harness.

Chest pocket

Chest pocket to keep essential items within easy reach.

Minimalist

This down jacket will provide the warmth you need 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.

Very good down jacket: comfortable and lightweight. The hood wraps nicely. I’ve used it for hiking so far. Warm and packs down really well. I recommend it!

Very pretty and comfortable. My usual size is M and it fits perfectly. It has a feminine cut and the color is exactly as pictured.
