It combines **windproof** protection with **water-repellent** performance while remaining pleasantly **breathable**, so you don't overheat on long road or gravel rides. The new, exceptionally **compact packable** main material makes the jacket so small it easily fits into a jersey pocket once the sun comes back out. Thanks to the **double-slider zip**, you can precisely control ventilation or quickly access your jersey pockets without fully opening the jacket. For Switzerland's typical weather changes – from Föhn to Bise winds – it counters with full protection even at the back, so spray and headwinds don't stand a chance. Elastic, highly breathable inserts on the sides and inner sleeves ensure a natural feel, keeping the **regularFit** cut sporty yet comfortable. - Windproof, water-repellent and breathable – ideal for cool, damp conditions between approximately +12°C and >+21°C. - New, exceptionally **packable** main textile for minimal volume in your jersey pocket. - **Double-slider zip**: ventilation from top or bottom and quick access to jersey pockets. - Complete back protection increases usefulness in wet conditions and on windy descents. - **regularFit** with highly elastic inserts on sides and inner forearms for a close-fitting, comfortable fit. - Main materials: Body 100% polyamide; sides, rear neck panel, lower sleeves 75% polyamide / 25% elastane. - **Eco DWR** finish repels water and increases weather protection without sacrificing breathability. ## Technical Details and Features For the S11 update, Assos uses a tightly woven main textile that reliably blocks wind and, thanks to **DWR** treatment, repels light rain and spray. In the technology overview, this main material is described as **Buster**; in the "Behind the product" section it's mentioned as **Breaker** – both designations refer to the new, densely woven, water-repellent S11 main textile. It's complemented by **Sens Air** inserts on the flanks and forearms, which increase freedom of movement and improve microclimate control. The close-fitting **regularFit** construction reduces seams, minimizing friction points while pedaling. The **double-slider zip** further extends climate control, for instance on long Swiss Alpine descents when quick, finely tuned ventilation is needed. Thanks to higher **compressibility** compared to its predecessor, the jacket disappears effortlessly into a jersey pocket when conditions turn drier or warmer. ## Applications and Benefits Whether it's brisk road rides along the southern Jura foothills, gravel tracks in the Mittelland, or commuting around Lake Zurich – this jacket shows its strengths wherever windchill and changeable showers are part of everyday riding. It's designed for **windy conditions** and cool temperatures and works as a standalone layer over your summer jersey or as weather protection over a warmer spring/autumn jersey. When it's breezy at the pass, close it completely; on the descent, open the **zipper** from below for controlled ventilation without sacrificing access to your rear pockets. When rain picks up, the **back protection** scores with better defense against spray than earlier, more ventilated rear panels. Because it's so **compact packable**, you'll simply take it along on uncertain rides "just in case" rather than deliberating. It's available from us in **two variants**, so you can choose style and application to match your setup. ## Size, Fit and Layering The UMA GT Wind Jacket S11 is designed with a **regularFit**: close-fitting but not restrictive, so it sits cleanly both over a short-sleeve jersey and over a mid-weight insulation layer. The elastic inserts on the sides and forearms prevent flapping and ensure the jacket lies smooth in typical riding position at the handlebars. Combine it during Swiss spring/autumn with lightweight arm warmers or a spring/autumn jersey; in strong winds, often just a base layer underneath is enough. Thanks to the **double-slider zip**, you can quickly adjust ventilation on long climbs or in the city. For added versatility, we recommend always carrying the jacket in your jersey pocket – the small pack size makes it possible.
