Our impossibly light RSR Jersey S11 replaces the RSR SUPERLÉGER S9. The hyper-cooling main textile remains unchanged, but a new, lighter warp-knit textile on the sleeves wraps the upper arms in bi-stretch support for second-skin, low-volume aerodynamics. The S11 generation supports longer rides with a full complement of Triple Ramp Pockets, matching the long-distance performance of the RSR Bib Shorts S11. A shorter body length improves fit in aggressive riding positions and reduces wrinkling across the stomach, and the refined collar shape enables full, deep breathing during high-intensity efforts.
