Assos Equipe RSR Short Sleeve Jersey S11

The Assos Equipe RSR Short Sleeve Jersey S11 sits at the top of the Assos Racing Series lineup — the brand's lightest and most aerodynamic short sleeve jersey, built for riders who need maximum performance in hot, high-intensity conditions. This is a race-day garment shaped by WorldTour input, not a training piece dressed up in race clothing. If you spend time in aggressive positions and demand a fit that moves with you rather than against you, this is where Assos focuses its engineering.

The main body is constructed from Hill Rombo, an open-structured circular knit designed for extreme breathability and active cooling — the kind of textile that earns its place on long summer road races and hard criterium efforts alike. The 550CX sleeve fabric takes a different approach: compressive, aerodynamically oriented, and rated to UPF 40 for sun protection during long days in the saddle. The torso is cut shorter than standard to minimize fabric bunching when you're low on the bars, and the collar geometry is shaped to keep your airway unrestricted when breathing hard. A Stabilizator V11 rear panel gives structure to the three rear pockets, keeping them functional under load. Finishing details — bonded raw-cut sleeve edges, a zipperless front closure, and the PILtec Plug-In hem — reflect how much thought Assos has put into eliminating friction points between rider and jersey.

Design Benefits

1. Engineered for aggressive riding positions: The shortened torso cut and second-skin racingFit work together to keep the jersey smooth and wrinkle-free when you're stretched low over the bars — whether you're climbing out of the saddle or holding a time trial position for extended efforts.
2. Ventilation where it counts: Hill Rombo's open circular knit structure is designed to move heat and moisture away from the body efficiently, making this jersey well-suited for summer road racing and high-output rides where thermal management directly affects performance.
3. Details that remove distraction: Bonded raw-cut sleeves eliminate bulky hems against the arm, the zipperless front keeps the chest profile clean under a skinsuit or jacket, and the PILtec hem is designed to stay anchored without digging in — so the jersey stays out of your mind while you focus on the ride.
