Assos EISENHERZ Ultraz Winter Jacket S11

The Assos Mille GT EISENHERZ Ultraz Winter Jacket S11 is their most advanced winterproof jacket to date. It’s engineered for the harshest winter days when other cyclists may resort to the indoor trainer, but you’ll be outside on your bike building your base fitness.

Advanced materials

It takes mental fortitude to get outside when you know you’ll be cycling in the wet and the cold. But with the EISENHERZ Ultraz, you’ll benefit from Assos’ textile know-how to keep you fully protected. It starts with the all-new AIRBLOCK-EVO.888 softshell. This highly flexible material blocks wind, cold and rain while remaining highly breathable. It’s ideal for winter rides where the pace can vary, keeping you warm when the pace is slower and steadier but letting sweat escape when you’re tackling tough climbs.

Beneath the stormproof shell, Assos uses its thermal waffle-structured HEATER textile. Its grid structure creates pockets of insulating warm air while allowing for greater air circulation to regulate your body temperature and draw moisture away from your skin.

ZigZaggy textile technology 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.

Assos regularFit

Thanks to the regularFit, the EISENHERZ Ultraz Jacket provides perfect comfort for longer winter rides while being streamlined enough to ensure you’re not wasting watts. There’s also an update to the waist and chest construction, boosting comfort on more upright bike geometries. Assos Louvre Tec design also reduces wrinkling and excess material on the sleeves.
