NanoShell 160g

This fabric features a dual-layer construction with merino wool on the inside for excellent thermoregulation and polyamide on the outside for enhanced durability. With a weight of 155 g/m², combined with a Drytech C0 water-repellent treatment, it provides ideal protection. In practice, the hollow fibers of merino wool can absorb up to 20% of their weight in moisture, which is then warmed by the body, creating an effective thermal barrier against the outside, similar to a neoprene wetsuit.

This strategic body mapping, based on areas of heat loss, involves placing fabrics with different thermoregulation and breathability properties in key zones. The upper torso and shoulders use a higher-weight fabric to maximize warmth, while low-loss areas such as the sides are made with a more breathable material. The result is the perfect balance of thermoregulation, breathability, packability, and lightness.

With a weight of 250 g/m², the fabric of this jacket features a dual-layer construction with merino wool on the inside for excellent thermoregulation in cold conditions, and polyamide on the outside for enhanced durability. Combined with its Drytech C0 water-repellent treatment, this fabric is ideal for an ultra-versatile jacket. With 100% stretch in the warp and 80% in the weft, it adapts to the volume of your pack if you choose to wear the jacket over it.

Placed along the sides, this fabric enhances the jacket’s packability and lightness while maintaining its windproof properties. Thanks to its very tight weave and a weight of just 107 g/m², it promotes effective thermoregulation for the runner. Its Drytech C0 water-repellent treatment also provides additional protection against light rain.

The dimensions of this pocket have been carefully designed to allow the jacket to be packed into itself, making it easy to slip into your belt or pack. Simple and intuitive to use, you just need to fold the jacket into the pocket to instantly reduce its volume. Located at the back of the jacket, under the hood, this pocket also allows you to store the hood when not in use.

The front of this hood is intentionally more rigid to create a protective visor against light rain. Compatible with a beanie or a cap, this panel adds structure for a fit that follows your head movements, allowing you to stay focused on the terrain.

Whether at the hem of the jacket or around the hood, this seamless bonded finish eliminates friction for unmatched comfort. In addition to its clean, minimalist design, it slightly limits the fabric’s elasticity at the edges for an optimal fit and drape.

Positioned on the side of the jacket, this pocket is designed to hold lightweight items such as gloves or a bandana while running. When stationary, for example at a refuge, it can also be used to store essentials you want to keep within reach, such as your headlamp or phone.

Positioned on the front of the jacket, these large, ultra accessible pockets are designed to store items commonly used during bivouac. Headlamp, gloves, beanie, everything stays within easy reach. While you can carry a few lightweight items while running, such as a bandana, these pockets are primarily intended for use during rest periods.

Minimalist and intuitive, this elastic drawcord with cord lock allows you to tighten the back of the hood for a precise fit and maximum protection against the wind.

Made with EverdryAero™ fabric, this headband ensures a secure hold of the hood, even in strong winds.

Minimalist and intuitive, this elastic drawcord with cord lock allows you to tighten the bottom of the jacket to reduce heat loss.
