THE SIGMA SHELL° IS THE MOST BREATHABLE WINDPROOF JACKET ON THE MARKET (>100k MVTR)
Windbreaker
Ultra breathable (>100k MVTR)
Ultra light (95 g in M)
Water repellent
Breathability >100k MVTR
*The MVTR unit measures the quantity of water vapor that the fabric lets pass in 24 hours, expressed in g/m2/24h. The higher this number, the more breathable the material. As an indication, a waterproof membrane will be between 5000 MVTR and 30,000 MVTR for the most breathable.
We have selected an extremely fine and breathable material (54g/m2) to which we have applied a thermo-mechanical treatment to tighten the fiber mesh, giving it a windproof property.
Drytech C0 water-repellent treatment
Thanks to a Dry Tech C0 treatment coupled with the quick-drying property of the Everdry material, the Sigmashell° will protect you from small and brief showers and will dry quickly.
ULTRA LIGHT (95g in M) AND ULTRA COMPACT (250 mL)
In order to optimize the compactness and lightness of the jacket, we opted for a half-zip, and an ultra-light material of 54 g/m2.
The jacket finally fits into a small 250 mL pocket provided for this purpose.
French material and Portuguese manufacturing
The ultra-light material manufactured in Ardèche from A to Z emits up to 12 times less CO2eq than its competitors for this type of product.
The jacket is assembled in Porto in a state-of-the-art factory, which runs 100% on renewable energy.

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

Is the jacket durable?
Is the jacket durable?
This jacket will perfectly resist a bag or abrasion (eg: falling on a rock).
On the other hand, it remains our lightest and therefore most fragile jacket in our range.
Its extreme lightness makes it vulnerable to damage that could be caused by a bramble or barbed wire.
In these cases, this can affect its aesthetics (snag, pulled thread) but not its effectiveness.
It is not recommended to consider an adventure in the Corsican maquis with it!
But a ride on the Thor of the Giants or the Echappée Belle will pose no problem for him.
Does the jacket have pockets?
Does the jacket have pockets?
The extreme lightness and elasticity of the material makes it unsuitable for carrying weight.
This jacket therefore has no pocket, apart from the storage pocket.
The absence of a pocket allows the passage to gain in compactness.
What is the difference with NanoShell?
What is the difference with NanoShell?
Unlike the Sigma Shell, the NanoShell will stand out by:
- Warmer thanks to the use of a Merino material (would be used when it is 5 to 10°C cooler compared to the Sigma Shell°)
- A little less compact (330 mL) and a little less light (160g)
- A full zip
Is the jacket unisex?
Is the jacket unisex?
Yes, this jacket is cut to suit both male and female body types.
Ladies, consider taking the jacket one size smaller.

A word from the founders
“It was on these trails that we met... In 2019, we realized that we did not agree with what was written on the labels of our clothing. And it was not possible to find trail clothing that was both technical and eco-responsible.
So we put everything together to create the outfit of our dreams. The one that covers more km on our shoulders than in a boat!”
