    85% polyester, 15% polyurethane 195g/m², waterproof (20.000mm H2O), breathable (20,000g/(m²·24h)), and 100% windproof. Ecological DWR (Durable Water Repellency) treatment free of PerFluoroCarburos, repels rain and snow, protecting the membrane from water saturation, thus facilitating its breathability.

    Note that although the fabric it is waterproof, the seams (like the zippers) are not heat-sealed due to the construction of the fabric StretchShell, so the jacket is not waterproof.

    Fabric with a high component of Kevlar® and Fiberglass specially designed to resist lateral cuts from skis as well as holes and snags caused by crampons. Optimized size to cover the areas of greatest friction without disturbing.
