The fleece component is designed to trap air thanks to the volume created by its texture; the air acts as a natural insulator, keeping the body warm. It is the brushing of the knit fabric that traps the air.

The woman's Forclaz 50 represents the following benefits per year:

10 million plastic bottles (1 litre) recycled
621 tonnes less waste for the planet
43% water saved*
58% energy saved*
54% less CO2 emissions for the planet*

This is the added value of recycled polyester.

*Compared to the previous models made of non-recycled yarn

We test the ageing of our hiking fleeces to guarantee their durability. We guarantee:
- resistance to abrasion from the backpack and arm movements, thereby delaying the pilling that is a feature of this material
- the durability of the seams
- the resistance of the fleece material after 3 washes (dimensional stability)
- colour fastness after washing, when exposed to UV light or after contact with perspiration.
