UMA GT EISENHERZ Ultraz Winter Jacket S11

The EISENHERZ S11 jacket, our most advanced extreme winter model to date, is one of the latest additions to the Ultraz line. It features the new AIRBLOCK-EVO.888 softshell fabric, a breathable and highly elastic material that adapts to the contours of the body and blocks wind, cold, and rain. Beneath this flexible fabric is a new thermal fabric, which has a grid structure to trap heat pockets and increase breathability. The new sleeve design incorporates softshell fabric and single-layer insulation, making it easier to layer with an insulated base layer and Ultraz Winter Gloves. Pair this jacket with the UMA GT EISENHERZ Ultraz S11 Winter Bib Tights, Ultraz Winter Base Layer, and ASSOSOIRES on the coldest, wettest days of mid-winter. Featuring a streamlined comfortFit cut, this jacket is designed for the most extreme winter weather conditions. Its updated design reduces bulk and incorporates new fabrics that enhance breathability and stretch while maintaining full weather protection. FEATURED FABRICS: The main fabric is AIRBLOCK-EVO.888, a proprietary, weatherproof softshell material originally developed for the Racing Series. Its high stretch and breathability make it ideal for this jacket. The waffle-knit HEATER fabric features channels that trap insulating micro-pockets of heat, while also promoting breathability and actively wicking moisture away from both the skin and a base layer. ZigZaggy fabric, another technology inherited from the Racing Series, has been used as insulation in the sleeves: this material, which includes a water-repellent and windproof side, wraps the arms in a streamlined design.
