MILLE GT Shell Jacket S11

Assos MILLE GT Shell Jacket S11

The MILLE GT Shell Jacket S11 is your reliable companion for changeable Swiss weather – from quick after-work loops to long Alpine descents. The new Hurricane textile combines windproof and water-repellent protection with enhanced breathability, so you won't get steamed up even when pushing the pace. Thanks to regularFit, the shell fits comfortably over summer jerseys or winter jackets without flapping or bulking up. It packs down small and fits in your jersey pocket – ideal when dark clouds suddenly roll in over Lake Zurich or the Jura. The extended collar and hem keep out drafts and spray, which is especially pleasant on wet roads. Ultra-elastic Sens‑WR inserts seal at the wrists and work seamlessly with gloves. Reflective details on shoulders and lower back increase your visibility in twilight and fog.

Technical Details and Features

Assos uses Hurricane textile in this S11 generation, which combines an ECO DWR barrier with windproof protection and breathability. The shell repels precipitation and road spray while wicking moisture from inside to outside, preventing a humid-warm microclimate from forming. The Sens‑WR cuffs wrap seamlessly around the wrists, block spray and enable smooth layering with winter gloves. The regularFit construction uses highly elastic fabrics that embrace the body without bulking up, which is noticeable on long training rides. An extended collar and hem provide additional protection for exposed areas, especially on cool descents or drizzle. Reflective details increase visibility in diffuse light, when wind and rain protection matter most. Material specifications: main fabric 100% polyester, sleeve inserts 73% polyamide and 27% elastane.

Applications and Benefits

In summer, the jacket sits ready in your jersey pocket in case storms threaten or long, cool descents await. In spring and autumn, you layer it over a medium-weight spring-fall jersey for additional weather protection and stable thermoregulation. In winter, it forms the outer barrier over your warm cycling jacket – optimal for wet, windy conditions in the city and countryside. For commuters around Zurich, the compact shell offers reliable protection during changeable morning hours. On pass rides, the extended back keeps spray away while the collar blocks unpleasant drafts. The sleek regularFit cut runs smoothly even in crosswinds and noticeably reduces flapping. Reflective elements support visibility in twilight, fog and on wet roads.

Fit and Layering Tips

The regularFit silhouette is designed for comfort on long rides and hugs close through elastic textiles without restricting you. Wear the shell in summer directly over short-sleeve jerseys and combine it in transitional seasons with a Spring Fall layer for better thermal balance. In winter cold, it works as the outermost layer over your thermal jacket and helps reduce windchill. The Sens‑WR cuffs lay cleanly over or under gloves and prevent cold bridges. At speed or in crosswinds, the jacket stays pleasantly calm thanks to reduced excess material. The reflective elements on shoulders and lower back provide better visibility in grey daylight as well as in drizzle and fog. Available in four variants so you can choose your style to match the rest of your kit.

Material and Technology Background

Assos uses Hurricane in other weather protection pieces too and describes it as a softshell textile focused on wind and rain protection plus active moisture transport. In this shell, the emphasis is on water-repellent performance thanks to ECO DWR, without neglecting breathability. The combination of polyester main fabric and elastic polyamide/elastane inserts on the sleeves improves freedom of movement and closures. This setup targets versatile year-round use rather than rigid, heavy winter membranes. The approach supports a dry body climate on long rides, even when the weather turns. This keeps the shell light, packable and practical for everyday use – from after-work rounds to weekend classics.
