Assos RS EF Jersey GIRO
When you choose the Assos RS EF Jersey GIRO, you aren't just wearing a team kit; you’re donning the exact RS S11 platform engineered for the world’s elite. Blending high-concept design with raw speed, this jersey is engineered for the rigours of racing.
The sleeve construction has been meticulously refined to be even lighter than previous iterations, ensuring a compressive, second-skin fit that eliminates drag. This new textured material is specifically tuned for aerodynamic gains, slicing through the air while you maintain an aggressive riding position on the drops.
Advanced Engineering for Total Stability
At the heart of the jersey is the miniCheck Tex main body fabric, renowned for its ultralight, highly breathable properties that provide body-wrapping support during intense efforts. To ensure the jersey remains perfectly positioned during explosive sprints or steep climbs, Assos has integrated the innovative PILtec Plug-In technology. This system utilises an ultralight textile strip paired with silicone microdots at the rear hem, guaranteeing a stabilised fit that won't budge even when damp with sweat or rain. Whether you’re cornering at speed or pushing your limits at a Gran Fondo, this jersey provides the technical edge required to go beyond.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
