It combines a **CORE Light Softshell** at the front with a water and windproof membrane at shoulders and chest, and uses the elastic insulation **LITHIUM Medium** at the belly. At the back, an extremely breathable panel made from **SENS Air Plus** ensures that excess heat can escape quickly. The close-fitting elastic **regularFit** cut sits calmly without pressing or flapping, supporting both long training sessions and quick after-work rides around Zurich. Thanks to the **Double Slide Zipper**, ventilation can be finely controlled from top or bottom – practical on climbs or for quick access to jersey pockets. The vest is part of the Assos **ClimaCode 2/3 (Spring-Fall)** line and was explicitly developed for three seasonal windows. - **CORE Light Softshell** at front with wind and waterproof membrane at shoulder/chest for storm-proof front coverage. - **LITHIUM Medium** at belly for breathable, elastic warmth without bulk. - Back made from **SENS Air Plus**: ultralight, highly breathable and temperature-regulating. - **Double Slide Zipper** for ventilation from top/bottom and quick access to pockets. - **regularFit** with body-mapped, highly elastic construction and **raw-cut** arm openings for friction-free layering. - Composition: Main material 49% Polyamide / 35% Polyester / 16% Elastane; Back 76% Polyamide / 24% Elastane; Front lower 83% Polyamide / 17% Elastane. - Available from us in **4 variants**. ## Technical Details and Features At the core of the vest is the three-layer **CORE Light** softshell, developed as the successor to the AIRBLOCK-EVO family, combining four-way stretch with breathable membrane plus **ECO** water repellency. This material blend shields rain and headwind at the front and silkily wicks moisture from the inside. **LITHIUM Medium** contributes as grid-structured insulation to active thermoregulation without restricting mobility. The back panel made from **SENS Air Plus** keeps the microclimate stable when power increases or weather changes. The **regularFit** geometry is tuned for long base kilometres and comfort-oriented rides, with slightly increased aerodynamics within the GTS line. Additionally, the **Double Slide Zipper** provides precise dosing of airflow as well as access to nutrition and tools, while **raw-cut** edges facilitate layering with long-sleeve jerseys or arm warmers. ## Applications and Benefits The MILLE GTS 2/3 Vest S11 shows its strengths everywhere you need protection at the front and active breathability at the back – from wet summer rides to cool morning rides in spring and autumn. On road, gravel and commuting routes in Switzerland, the **softshell front** efficiently keeps wind and spray at bay, while the back panel prevents overheating on uphill sections. Thanks to the low volume at the arm openings, the vest can be easily pulled over a **Spring/Fall** jersey or worn under a light rain layer. The **two-way zip** supports fine-tuning of temperature on climbs and closes cleanly at the bottom so the vest sits calmly at speed. The fit remains stable even with fully packed jersey pockets, which is particularly convincing on longer rides in the Mittelland or through the Zurich Oberland. For changeable tours, it offers a noticeable comfort and safety gain with reliable visibility of back pocket access. ## Sizes, Variants and Care Instructions According to the manufacturer, the vest is available in sizes XS to 3XL and in timeless colours like **blackSeries** as well as **Terra Sand**, so it integrates seamlessly into existing kit combinations. The **4 variants** we offer cover typical Swiss application scenarios in **Spring/Autumn (2/3)**, from quick training to daily commuting. For a long lifespan, we recommend drying away from direct heat after rides and regular, gentle washing with functional detergent; the **ECO** treatment of the softshell sustainably supports weather protection. Assos also provides a 2-year warranty for the product line, which underlines the quality of the materials. ## Variants - 11.34.422.18.M: in stock - 11.34.422.18.L: in stock - 11.34.422.18.XL: in stock - 11.34.422.18.S: in stock - 11.34.422.18.2XL: in stock - 11.34.422.18.XS: in stock --- Source: https://kilometro.ch/en/products/rain-wind-protection-662/mille-gts-23-vest-s11-783
