A streamlined regularFit jacket for winter’s harshest most extreme conditions. The updated construction reduces volume throughout and new textiles increase breathability and elasticity while maintaining complete stormproof protection. The most advanced of our extreme winterproof jackets to date the EISENHERZ S11 updates the Ultraz line with the all-new AIRBLOCK-EVO.888 softshell which is a highly elastic breathable textile that conforms to body contours while blocking wind cold and rain. Beneath that supple shell is a new thermal textile which uses a grid structure to trap pockets of warmth and increase breathability. The new sleeve construction combines insulation and softshell protection in a single layer making it easier to layer with an insulating skin layer and Ultraz Winter Gloves. WHEN/HOW TO USE IT For the coldest wettest conditions of deep winter pair with the MILLE GT EISENHERZ Ultraz Winter Bib Tights S11 and the Ultraz Winter Skin Layer and ASSOSOIRES.
