Technical information


Duck down containing 90% down and 10% feather with a fill power of 700 Cuin (IDFB standard). The jacket's assembly has 3D partitioning.

*Duck down traceability ensured by the “Responsible Down Standard” certification. This allows us to guarantee that our down comes from ducks raised for their meat, that were neither force-fed nor plucked alive:


Our jackets are lab-tested in a climatic chamber to establish the temperature ratings.
For moderate activity in a 5 km/h wind, this jacket is suitable for temperatures down to -29°C.

Pockets and bags

This jacket contains:
- 2 outer hand-warmer pockets. - 2 outer chest pockets accessible when wearing a harness + 1 flap pocket inside to hold a phone.
- 2 mesh pockets inside the jacket to keep a spare pair of gloves warm or for a flask.
- 1 stuff sack to store the jacket while out on the mountain.


Down hood designed for wearing over your mountaineering helmet, adjustable with two systems at the front and back of the jacket.


Durable component has been selected to reinforce the jacket's forearms. Indeed, when mountaineering, these areas are subject to significant stress. The component selected is more robust than the main component of the jacket.
