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.Specifications:- Weight: 66kg - Compositions: Main Fabric 73%Polyamide 27%Elastane, Sleeve 80%Polyamide 20%Elastane, Back 75%Polyamide 25%ElastaneTechnology:Construction/fit:- Our AEPD 11 racingFit is a second-skin, aerodynamic silhouette designed with WorldTour feedback to envelope the body in 360-degree compression and stability.Double Slide Zipper: - A two-slider construction that allows easy access to pockets and ventilation from top or bottom.ASSOS aeroScience: - Combining thermoregulation and stormproof protection with pure racing aerodynamics.
