An upgraded take on the classic gilet engineered at the request of professional athletes to provide the protection of an all-weather vest with the coverage and fit of a racing jersey. The product of ASSOS aeroScience and a collaboration with the Tudor Pro Cycling Team the RS Shell Jersey S11 completely re-imagines what a gilet can do – a highly breathable stormproof shell that protects like a vest but fits like a racing jersey. The all-new DIAMOND Ultra softshell shields the front and shoulders from wind chill and precipitation and the high-stretch insulating 575CX textile wraps the upper arms in thermoregulating support. Both textiles are highly breathable keeping your microclimate dry and ensuring that full-gas efforts don’t leave you riding in a clammy chill. They’re also both ultra-elastic and the addition of an elastic mesh panel on the lower back supplements fit and visibility of numbers pinned to your jersey allowing for a second-skin aerodynamic silhouette suitable for competition at the highest levels. As ride conditions improve and the temperature rises the RS Shell Jersey S11’s low-volume construction packs down to stow in a jersey or jacket pocket. Composition Main Fabric 73%Polyamide 27%Elastane; Sleeve 80%Polyamide 20%Elastane; Back 75%Polyamide 25%Elastane The finer details FEATURED FABRICSDIAMOND Ultra is a new proprietary 2L membrane that represents a more protective more elastic upgrade to our SPHERE softshell family. This highly elastic textile is our lightest DIAMOND material and it confers premium breathability waterproof protection and a second-skin pressure-free fit. 575CX is an insulating breathable warp-knit textile that wraps the contours of the body in supportive second-skin compression. CONSTRUCTION/FITOur AEPD 11 racingFit is a second-skin aerodynamic silhouette designed with WorldTour feedback to envelope the body in 360-degree compression and stability.
