SIGMA SHELL° IS A RADICAL APPROACH TO THE WINDSHELL CONCEPT
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)
SIGMA SHELL° IS THE MOST BREATHABLE WIND PROOFING JACKET ON THE MARKET (>100k MVTR)
ULTRA LIGHT (95g in M) AND ULTRA COMPACT (250 mL)
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.
A 54 g/m2 SIMILI MEMBRANE
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.
BREATHABILITY UNRIVALLED ON THE MARKET
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.
DRYTECH C0 WATER-REPELLENT TREATMENT
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.
INHERENTLY SUPER STRETCH
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.
1ST, 2ND OR EVEN 3RD COAT
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.
A COMPLETELY SOUNDPROOF MATERIAL
This monolayer eliminates the usual rubbing noise characteristic of membrane jackets.
VERY LOW ENVIRONMENTAL IMPACT
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.

Frequently asked questions
Why pre-order?
Why pre-order?
Conventional in-store distribution generates an average of 20% end-of-season waste.
Pre-ordering online is a new way of consumption that eradicates waste by producing only what is necessary.
But it also allows us to raise the necessary funds to launch the production, essential financing for a small brand like us!

How durable is the jacket?
How durable is the jacket?
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.
Does the jacket have pockets?
Does the jacket have pockets?
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.
What's the difference with NanoShell?
What's the difference with NanoShell?
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

A word from the founders
"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!"
