MILLE GT Women's Ultraz Winter Jacket S11 EVO

A storm-proof winter cycling jacket for extremely wet and cold weather. The updated S11 EVO version is warmer than its predecessor and offers greater freedom of movement at the chest, neck, and arms. The fit remains slim without any excess volume, while a more elastic construction and small adjustments to the collar, shoulders, and chest provide noticeably more room.

Technical Details and Features

Ultraz Protection starts with a twinDeck front panel that combines AIRBLOCK-EVO.888, a storm-proof softshell, with an inner lining made of HEATER – an insulator with a waffle structure that traps microscopic pockets of warm air and actively wicks away moisture. The new CORE Medium textile is used on the sleeves. CORE Medium is the most insulating softshell in the CORE family, whose breathable membrane and ECO water-repellent treatment protect an especially soft insulating layer, combining storm protection with warmth. The back and forearms are made from RX EVO Plus, a material that enhances breathability and elasticity while providing dry warmth through thermal properties and an ECO water-repellent treatment. The regularFit cut with an anatomical design reduces seams, minimizing friction for added comfort when layering. According to the manufacturer, the jacket is suitable for temperatures between minus eight and plus three degrees, with an insulation rating of 5 out of 5 and wind protection of 5 out of 5.

Applications and Benefits

This jacket is built for Swiss winters, when rain, wind, and cold hit all at once and reliable protection is essential. Reflective details on the pockets and logos boost visibility in poor lighting conditions, which are common on overcast winter days. The Triple Ramp pockets keep contents securely in place, even in splash water and precipitation. Whether you're planning long winter rides or facing tough training conditions, you'll benefit from the combination of warmth, mobility, and protection that this jacket delivers for road cycling in low temperatures.
