Assos MILLE GT Shell Jacket S11

Assos MILLE GT Shell Jacket S11

The Assos MILLE GT Shell Jacket S11 is a versatile, storm-proof all-season shell for road cycling, gravel and commuting, developed for changeable Swiss weather. It has been updated with a new windproof and water-repellent fabric while offering noticeably higher breathability. Thanks to its slim cut, it can be easily layered over summer jerseys, midlayers or winter jackets without flapping. At the same time, it remains compact and packable, disappearing into your jersey pocket in summer when needed – ready for surprise thunderstorms or cool descents. The extended collar and hem provide additional protection from spray, which is particularly helpful on wet roads and gravel tracks. Ultra-elastic cuffs seal at the wrists and work seamlessly with gloves.

Technical Details and Features

At the heart of the jacket is the new HURRICANE fabric, which combines ECO DWR treatment with windproof protection and high breathability. This combination reliably keeps out precipitation and spray while allowing moisture to escape from within, preventing a humid microclimate from forming. The regularFit uses highly elastic panels that wrap around the body and eliminate excess material – noticeably quiet and flutter-free on fast descents. Sens‑WR inserts at the cuffs improve sealing and make layering over or under gloves easier. Reflective elements on shoulders and lower back increase visibility when wind and rain protection are particularly important.

Applications and Benefits

As an all-round shell, the MILLE GT S11 is a logical choice for road cycling loops around Lake Zurich, gravel adventures in the Mittelland or commuting routes through the city. In summer, it fits in your jersey pocket and comes into play when thunderstorms threaten or on long, cool descents. In spring and autumn, it complements your Spring/Fall jersey with effective wind and wet weather protection without hindering thermoregulation. In winter, it functions as the outermost protective layer over your warm jacket, forming an effective barrier against wet, windy conditions. The extended collar and deeper back keep spray away – practical on wet Alpine passes or the commute to work. Thanks to its compact pack size, it's always there without wasting space in your jersey or saddle bag.

Fit, Variants and Material

The regularFit geometry is aimed at endurance riders who want comfort and freedom of movement without unnecessary bulk. Two subtle colour options – blackSeries and Bronze Ash – blend discreetly with existing GT layers. The size range from XS to 3XL covers a broad spectrum and makes choosing the right layer for training and everyday use easier. The main material consists of 100% polyester, with elastic sleeve inserts made from 73% polyamide / 27% elastane for a clean, close-fitting finish. This creates a durable, easy-care setup that reliably protects for many seasons and integrates versatilely into your layering system.
