Technical information

Sizing information

Quite a close-fitting cut. Inner volume lets you wear a second lightweight layer underneath, such as a microfleece top.

Thermal comfort and windproof

The wind makes you feel considerably colder.
With an outside temperature of 0°C and 20 km/h winds, it will feel like the temperature is -10°.
"Windproof" components fight the uncomfortable effects associated with this "freezing effect". Forming a barrier against the wind, they effectively reduce heat loss.

Protective details

Drawstring tightening with toggles at the bottom of the jacket

Tightening at the cuffs with Velcro tabs

Adjustable hood

Water-repellent property of component (not to be confused with waterproofing)

The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it.
This prevents the fabric from soaking up water and keeps it lightweight and breathable.
The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.
To reactivate it, follow the guide:

Recommended additional product

Wash-in waterproofing product that restores the water repellent properties

It restores the water repellent properties of the fabric and optimises the performance of your garment throughout its lifetime.

Additional sustainable development information

We use "micro-grid" fleece lining with 100% recycled polyester thread.

User Directions

Not waterproof: not for use in rain.


In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team tested this jacket for 4 days in the southern French Alps (Lus La Croix Haute). You can expect wind, rain, a bit of snow, a bivouac... and a lot of fun! We were then able to make the final modifications and validate it for use for mountain trekking.
