Assos Uma GT Short Sleeve Jersey S11 EVO

The Assos Uma GT Short Sleeve Jersey S11 EVO is the foundation of the Assos women's Endurance series — a lightweight, highly breathable cycling jersey engineered for warm-weather riding above 70°F. The EVO update brings a new sleeve fabric, a cleaner pocket construction, and an updated logo, while keeping the AirCell body that made the previous generation a summer staple.

The body is built from AirCell, an ultralight circular knit with an open hexagon pattern purpose-built for airflow. Bistretch construction gives it elastic, body-wrapping support, and engineered odorControl maintains freshness during sustained effort. The sleeves introduce Eclipse, a new lightweight warp knit developed from the Racing Series — ultrasoft against the skin, rated UPF 50+, and finished with a raw-cut lie-flat edge that keeps the sleeve profile low and reduces drag. The Stabilizer V11 back panel stiffens under load, keeping the triple rear pockets from sagging even when fully stocked. Assos notes the jersey is so lightweight that applying sunscreen beneath the body panels is recommended on exposed rides.

The EVO's revised pocket system retains the Triple Ramp design — flexible "lid" panels that secure and stabilize contents — but with cleaner lines and a reduced seam count. Regular fit runs close to the body for minimal bulk under a jacket or vest, and the body-contoured shaping eliminates pressure points on long efforts.

Design Benefits

1. AirCell body fabric — open hexagon knit construction maximizes airflow and moisture transfer, keeping core temperature manageable on the hottest rides.
2. Eclipse sleeves with UPF 50+ — the new Racing Series-derived sleeve fabric adds sun protection and a lie-flat raw-cut finish that reduces aerodynamic drag without a hem band.
3. Stabilizer V11 back panel — structured back keeps Triple Ramp Pockets stable and accessible even when loaded with food and essentials on long rides.
4. Simplified EVO construction — cleaner pocket seam lines and reduced seam count compared to the previous generation, with the same secure ramp-style pocket system.

Final Take

The Uma GT Jersey S11 EVO is Assos's answer to the everyday hot-weather ride — not a race jersey, not a casual top, but a precision-built endurance staple that handles 70°F+ conditions with maximum breathability and thoughtful detail. Six colorways make it easy to find one that earns a permanent spot in your summer rotation.
