We started wearing the new RSR S11 during some of our hottest days on Marin’s longer climbs, those no-shade, full-send afternoons when there’s nowhere to hide and every layer gets put to the test. This jersey holds up. It’s lighter than the last RSR, faster to dry, and designed to disappear when your head's down and the pace is high.

The fit is unmistakably Assos...sharp, low-volume, and tailored for hard efforts in aggressive positions. The sleeves wrap with a smooth bi-stretch feel that supports the upper arm without pulling or pinching, and the redesigned body settles clean without any bunching at the waist. The open-knit fabric through the torso breathes better than anything else we’ve tried and resists odor well, even deep into multi-hour rides.

We also appreciate the expanded triple pocket layout. The added storage doesn’t ruin the silhouette, and it means this piece finally holds its own on longer days—not just crit laps or hill repeats. For us, this is the jersey we pull when the route is demanding, the forecast is full sun, and the goal is simple: go fast, stay light.
