The ASSOS Eisenherz S11 is an extreme winterproof jacket with advanced technology.  This Winter jacket 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.

TECHNOLOGY
FEATURED FABRICS
The main softshell is AIRBLOCK-EVO.888, a proprietary stormproof softshell developed for the Racing Series and featured here for its high elasticity and excellent breathability. The waffle-structured HEATER textile uses channels to trap micropockets of insulating warmth, promote breathability, and actively pull moisture from your skin or base layer. The ASSOS ZigZaggy fabric is also trickle-down Racing Series technology. It’s used on the sleeves for high insulation with a windproof, water-repellent face that wraps the arms in a streamlined fit.

CONSTRUCTION/FIT
ASSOS streamlined regularFit provides total comfort for long rides and cold-weather base miles. Updated waist and chest construction increase comfort in upright riding positions, and the ASSOS Louvre Tec design reduces wrinkling and excess material on the sleeves.

ENGINEERING
//twinDeck Tec: A double construction that layers soft insulation below a softshell membrane, adding protection in crucial areas.
//struzzoKragen: A collar of lighter, soft insulation with a comfort fit. Actively modulates the personal microclimate without requiring unzipping and exposing the throat to cold air.
//Reflective detailing: On the pockets and the forearms, reflectivity increases visibility in the low-light, overcast conditions when stormproof protection is most valuable.
//Triple Ramp Pockets: Flexible fabric panels sewn into the pockets secure and stabilize the contents while protecting against precipitation or road spray.
