For mountaineers and ski touring practitioners who need ultra-light emergency thermal insulation in their summit pack.

At the bivvy, at a route belay or stationary on snow, you need insulation that holds firm against gusts without weighing down the pack.

Those who won't tolerate a single unnecessary gram in their pack but refuse to sacrifice thermal protection when the cold sets in.

As an outer layer in cold, dry conditions, or as a mid layer under a hardshell in wet weather. Over a thermal base layer.

Alpine cut — your usual size.

Its lightweight build at 285g makes it the reference insulating layer for mountaineering and ski touring — the most compact 800-fill natural down for outings where every gram counts.

Lifetime repair

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

lighter, higher, further.

In ski touring, every gram in the pack is felt in the legs. In mountaineering, every added layer restricts mobility. A down jacket that is no longer a compromise was needed.

"It weighs 250g and packs into your hand.

Because the best layers are the ones forgotten in the pack until the critical moment. Extreme lightness, uncompromising warmth.

Il n'y a pas de choix Parapente dans les activités principales, c'est pourtant sa première utilisation du fait de sa légèreté et compressibilité en ce qui me concerne, puis viennent les autres activités montagne Randonnée, Alpinisme etc Très chouette produit et très bien taillé ?

pour l'instant par encore assez testée sur le terrain relativement conforme pour la taille M et mes 1m70 et 70kg bon rapport qualité prix par rapport à la concurrence, qui ne propose pas souvent un protège menton pour la fermeture à poids égal

Vraiment légère et compressible. Utilisée en actif l'hiver et statique l'été. Je n'ai pas encore assez de recul, mais le niveau de chaleur apportée semble correspondre à ce programme. Pour une veste orientée alpi, on pourrait presque attendre un double zip (l'existant fonctionne très bien à une main) pour l'utilisation du baudrier.
