Blackshell

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.

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.

This 54 g/m² fabric is a true technological achievement, offering the ideal balance between wind protection, breathability, and packability. It also features a mechanical treatment that tightens the fibers to enhance air permeability, along with a Drytech C0 finish. The result is one of the best materials for creating a highly breathable and ultra-compact windbreaker. Unlike conventional windbreakers, this fabric has no coating, maintaining a soft, silky feel with no noise.

This full front zip allows you to easily open the jacket to regulate temperature during effort and or access your pack. Its minimalist 3 mm design reduces weight and bulk, making the jacket lighter and easier to store in a trail running pack. It also provides quick and efficient ventilation while on the move.

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.
