A specialised impregnation method that does not contain harmful polyfluorocarbon substances. Gives garments water-repellent properties and effectively optimises the level of breathability of the material.

A technology that is used by the Jack Wolfskin brand in fleece, trousers, softshells, jackets, caps and gloves. STORMLOCK provides good breathability and 100% windproofness, with flexibility and better water protection than classic softshell jackets.

Jack Wolfskin's active moisture management technology absorbs moisture and wicks it away from the body, so the material dries quickly to protect against chilling.
