# EQUIPE RS Shell Jersey S11 > Assos EQUIPE RS Shell Jersey S11 - windproof and waterproof at the front, aero racing fit, packable & highly breathable - Price: 253.00 CHF - Brand: Assos - Category: Rain / Wind Protection - Availability: in stock - SKU: 11.32.428.18.2XL, 11.32.428.18.XL, 11.32.428.18.M, 11.32.428.18.L, 11.32.428.18.S, 11.32.428.18.XS ## Assos EQUIPE RS Shell Jersey S11 The Assos EQUIPE RS Shell Jersey S11 is a reimagined road racing layering solution that combines the **protection of a gilet** with the coverage and **race fit** of a jersey. It was developed as part of **ASSOS aeroScience** in collaboration with the Tudor Pro Cycling Team – with a focus on aerodynamics, thermoregulation, and weather protection without unnecessary bulk. At the front and shoulders, the new **DIAMOND Ultra Softshell** shields against wind, cold, and rain, while **575CX** at the upper arms provides elastic, thermoregulating support. Both fabrics are highly breathable and quick-drying, so you won't get cold even after intense intervals, and the low-volume construction packs down small into a jersey or jacket pocket. - DIAMOND Ultra Softshell front/shoulders, **stormproof** and highly elastic - **575CX** warp-knit at the upper arm for thermoregulation and **second-skin** compression - **AEPD 11 racingFit**: aerodynamic, close-to-body silhouette - **Double Slide Zipper** (two-way zip) for ventilation and pocket access - **Raw-cut** finishes at sleeves, hem, and zip for clean aero lines - Elastic **mesh panel** at the lower back for fit and race number visibility - Colour **blackSeries**, sizes **XS–2XL**, packable low-volume design ## Technical Details and Features At the heart of the weather protection is the two-layer **DIAMOND Ultra** membrane at the front and shoulders, combining breathability with elastic moisture protection, while **575CX** wraps the upper arms as an insulating, breathable warp-knit fabric. The **AEPD 11 racingFit** delivers 360-degree compression and WorldTour-level stability, supported by **raw-cut** edges with no seam bulk. Practical for race use: the **Double Slide Zipper** can be opened from the top or bottom – for precisely controlled cooling and quick access to the jersey pockets underneath. At the lower back, an elastic mesh panel improves fit while keeping your race number visible, reinforcing the jersey's race-focused design. Fabric composition as stated by the manufacturer: main fabric 73% polyamide/27% elastane, sleeves 80% polyamide/20% elastane, back 75% polyamide/25% elastane. ## Intended Use and Benefits The Shell Jersey really comes into its own at **high intensity** in changeable conditions – ideal for fast training rides, **races**, or mountain pass efforts where the front is fully exposed and the back needs maximum **breathability**. The sleeves minimise the typical gilet flutter at the shoulders and cuffs, contributing to **aero efficiency**, while the front reliably blocks rain and headwind. At the back, Assos deliberately opts for greater ventilation and less weather protection to prevent heat build-up; the two-way zip further helps with **fine-tuning your cooling** and accessing food on the go. When the weather clears, the **packable** jersey folds down small into your jersey pocket – perfect for Swiss spring and autumn days when conditions can turn on a dime. For the optimal use case, the manufacturer recommends layering it over a Racing Series jersey. ## Fit and Sizing The EQUIPE RS Shell Jersey S11 is intentionally cut **close-fitting** and optimised for the race position; the compression stabilises without restricting freedom of movement. It's available in **six sizes (XS–2XL)** and in the race colour **blackSeries**, which underlines its clear positioning in the race segment. The **raw, bonded edges** avoid thick seams and support the streamlined silhouette even when worn over a thin race jersey. Riders tackling long, fast blocks or events in unsettled weather will particularly benefit from the specific balance of front protection and back breathability. ## Layering and Usage Tips for Switzerland For fast **road rides** around Lake Zurich or intense intervals over exposed **Alpine passes**, wearing it over a lightweight race jersey is the way to go; on cooler starts, a thin base layer can help smooth out **thermoregulation**. The **Double Slide Zipper** keeps access to the pockets underneath quick and intuitive without disrupting the aero profile. On group rides in the rain, the **front membrane** handles the bulk of the protection while the breathable back panel keeps your temperature in check – a deliberately race-oriented trade-off. Once the sun comes out, the **low-volume design** tucks away neatly into your jersey pocket, making this jersey a reliable companion throughout the entire season. ## Variants - 11.32.428.18.2XL: in stock - 11.32.428.18.XL: in stock - 11.32.428.18.M: in stock - 11.32.428.18.L: in stock - 11.32.428.18.S: in stock - 11.32.428.18.XS: in stock --- Source: https://kilometro.ch/en/products/rain-wind-protection-662/equipe-rs-shell-jersey-s11-1141
