Who did we design it for?

For mountaineers and ski touring enthusiasts taking on long approaches and demanding routes without compromising between lightweight design and genuine protection.

For those who move fast in the mountains — ski touring, mountaineering, mixed routes — and need a jacket that keeps up the pace without weighing them down.

For those for whom a packable, high-performance jacket is an essential piece of gear, not a last resort.

How to wear it?

Wear directly over a technical base layer or layered over a light down jacket depending on the conditions.

Your usual size; the pre-shaped cut is designed for full arm mobility.

What makes it different?

Its lightweight design delivers maximum protection and high breathability in the range’s thinnest fabric, without compromising waterproofness. The jacket you never notice in your pack.

Protection that lightens your load without compromising your safety

In high mountain terrain, every gram counts. A pack that is too heavy can cost you the summit.

This jacket is designed for those who refuse to compromise between protection and lightness. It delivers reliable shield against wind and harsh weather while staying imperceptible in your pack and on the move.

It breathes with your effort to prevent overheating and fits every outing, from the approach to the summit.

Because in the mountains, going lighter should never mean compromising on protection: a jacket that keeps you safe without weighing you down.

Don't forget the hybrid bikers! On the road, this jacket offers complete comfort and is highly visible. My partner has had the same one for two years and is very happy with it, hence my purchase!

Parfait ! Merci pour les conseils de taille préalables à l'achat, ça a été très utile. Livraison rapide, produits conformes, qualité qui a l'air d'être au RDV. De surcroît, bravo pour l'engagement écologique et social, c'est clairement ce qui a déterminé mon choix d'acheter chez vous plutôt qu'ailleurs.
