EQUIPE RS Shell Jersey S11

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.
