Ultra-breathable (>100k MVTR) and ultra-stretch (60%) imitation membrane
Ultra-light (95 g in M) and ultra-compact (250 mL)
Dry Tech C0 water-repellent treatment
Soundproof material (no frictional noise)
To optimize the jacket's compactness and lightness, we opted for a half-zip and an ultra-light 54 g/m2 fabric.
The jacket is finally stored in a small 250-mL pocket.
These are called membrane-like, as opposed to conventional windbreakers made from membrane material (minimum 2 layers). The latter have the advantage of being compact and windproof, but also the disadvantage of not being very breathable.
On our Sīgma Shell°, the technology is completely different. Rather than laminating several materials, we have selected an extremely fine, breathable material (54g/m2) to which we have applied a thermo-mechanical treatment that tightens the fiber's meshes, giving it a windproof property.
With an MVTR* of over 100 k, the jacket is incomparably more breathable than any membrane jacket on the market.
*The MVTR unit measures the amount of water vapor the fabric lets through in 24H, expressed in g/m2/24h. The higher this figure, the more breathable the fabric.
As a rough guide, a waterproof membrane can be found between 5,000 MVTR and 30,000 MVTR for the most breathable.
Thanks to a Dry Tech C0 treatment combined with the fast-drying properties of Everdry fabric, this imitation membrane will protect you from short showers and dry in a flash.
Note that this does not make it a waterproof jacket.
Not being laminated with a rigid membrane, this mono-layer technology preserves the high natural stretch of the starting material (60% elasticity).
This brings real comfort and freedom of movement and use.
Thanks to its impressive stretch and breathability, this jacket can be worn next to the skin.
The protective nature of the imitation membrane makes it ideal for use as a 2nd or even 3rd layer (to protect against short-lived weather conditions), making it an ultra-versatile Windshell.
This monolayer eliminates the usual rubbing noise characteristic of membrane jackets.
This ultra-light material, made in Ardèche from A to Z, emits up to 12 times less CO2eq than its competitors in this product category.
The jacket is assembled in Porto in a state-of-the-art factory that runs on 100% renewable energy.

This jacket will stand up perfectly to a bag or abrasion (e.g. a fall on a rock).
On the other hand, it remains our lightest and therefore most fragile jacket.
Its extreme lightness makes it vulnerable to the damage caused by brambles or barbed wire.
In such cases, this may affect its aesthetics (snagging, thread pulling) but not its effectiveness.
It's not a good idea to plan an adventure in the Corsican scrub!
But a ride on the Thor des Géants or the Echappée Belle won't be a problem for him.
The extreme lightness and elasticity of the material make it unsuitable for weight-bearing.
This jacket has no pockets apart from the stow-away pocket.
The absence of a pocket also makes for a more compact design.
Unlike Sigma Shell, NanoShell stands out for :
- Warmer thanks to the use of Merino fabric (can be used when the temperature is 5 to 10°C cooler than in Sigma Shell°)
- A little less compact (330 mL) and a little lighter (160g)
- A complete zip
Yes, this jacket is tailored to suit both men and women.
Ladies, remember to take the jacket one size smaller.
The jacket weighs 95 g in M

"It was on these paths that we met... In 2019, we realised that we didn't agree with what was written on the labels of our clothes. And it was not possible to find a trail outfit that was both technical and eco-responsible.
So we threw everything away to create the outfit of our dreams. The one that travels more kilometers on our shoulders than in a boat!"
