## Assos MILLE GT EISENHERZ Ultraz Winter Jacket S11

The MILLE GT EISENHERZ Ultraz Winter Jacket S11 is Assos' deep winter cycling jacket for the harshest days between biting winds, drizzle and sub-zero temperatures. At its heart is the new **AIRBLOCK‑EVO.888** softshell, which shields against wind, cold and light rain while remaining exceptionally breathable and elastic. Underneath, the **HEATER** thermal textile with grid structure stores warmth and actively wicks moisture away from your **Skin Layer**. The sleeves combine insulating layer and softshell protection in one layer, which noticeably simplifies layering and reduces bulk. The no-nonsense **regularFit** sits comfortably on long base rides without unnecessary bulk. Available in two variants, **blackSeries** and **Foundation Green**, each in sizes from XS to 3XL.

- **AIRBLOCK‑EVO.888**: storm-proof, highly elastic softshell for reliable wind and weather protection with high breathability.
- **HEATER** inner layer with waffle structure: creates insulating micro air pockets and promotes moisture transport.
- **ZigZaggy** on the sleeves: warm, windproof and water-repellent surface with body-hugging fit.
- **twinDeck Tec** in critical zones: double-layer construction for additional cold protection without unnecessary bulk.
- **struzzoKragen**: soft, lighter insulation at the neck for active microclimate regulation without zip interference.
- **Triple Ramp Pockets** and reflective details for secure storage and better visibility.

## Technical Details and Features

Assos combines several proprietary textiles in this jacket to create a coherent cold protection system. The **AIRBLOCK‑EVO.888** outer layer follows your movements, blocks headwinds and repels spray without compromising breathability. Directly underneath, the **HEATER** thermal textile works with grid channels that trap warmth and efficiently transport moisture outward. The sleeves use **ZigZaggy**, a Racing Series technology that combines high insulation with a windproof, water-repellent surface. At strategic points, **twinDeck Tec** increases protection, while the **struzzoKragen** finely controls your personal **microclimate**. The updated waist and chest layout with **Louvre Tec** reduces wrinkle formation, the **regularFit** offers long-distance comfort. Material composition according to Assos: 41% polyamide, 41% polyester, 18% elastane.

## Applications and Benefits

The EISENHERZ Ultraz S11 is your choice for deep winter days in Switzerland – from foggy lowlands to windy pass rides. It supports calm base rides as well as longer commutes when reliable **cold protection**, **wind protection** and regulated **breathability** are required. Thanks to the single-layer sleeve construction, it combines effortlessly with an **Ultraz Winter Skin Layer** without adding bulk at the arms. In very cold, wet conditions, the setup with **MILLE GT EISENHERZ Ultraz Winter Bib Tights S11** and matching ASSOSOIRES is recommended. The three **Triple Ramp** back pockets keep energy bars, phone and gloves secure, even on rough roads. Reflective elements on pockets and forearms increase your visibility in twilight and overcast conditions. The two colour variants **blackSeries** and **Foundation Green** cover subtle to sporty aesthetics.

Further notes on fit and layering: The **regularFit** is deliberately streamlined but not race-tight, making it ideal for **base kilometres**, winter commuting and gravel rides. For maximum thermal performance, start with a close-fitting **Skin Layer**, add a light midlayer if needed, and finish with the EISENHERZ S11. On the coldest days, the warmer **struzzoKragen** works excellently with a thin neck warmer. At temperatures around freezing, you'll appreciate the benefits of **AIRBLOCK‑EVO.888**, which significantly reduces windchill without overheating you. When choosing size, ensure a body-hugging fit so the **HEATER** grid structure works efficiently and the pockets sit stable. For deep winter setups, Assos recommends combining with **Ultraz Winter** Skin Layer, gloves and overshoes from the same line.
