Assos Uma GTV Short Sleeve Jersey S11

The Assos Uma GTV Short Sleeve Jersey S11 sits at the top of the UMA GT women's endurance line — re-engineered from the ground up with a lighter body textile, improved pocket construction, and the same meticulous fit refinement that has defined Assos apparel for decades. This is the jersey Assos designed for long days in the heat, where breathability and comfort compound in importance over the course of four, five, six hours in the saddle.

The central upgrade in this generation is the Sens Air textile — an ultralight, ultrabreathable fabric that runs cooler and feels softer against the skin than the previous GTV body material, while still providing UPF 50+ sun protection. The Stabilizer V11 back panel complements it with targeted structure across the rear, extending upward to the shoulders to keep pockets stable and prevent the sag and lateral movement that happens when rear pockets carry a full load of CO2, fuel, and hydration packets. The result is a jersey that stays neat on the back regardless of what you're carrying.

Fit is Assos's regularFit — engineered specifically for the long-ride position — and here it's refined further with LouvreTec construction: set-in sleeves combined with strategic darting at the collarbones and across the back remove excess material that would otherwise bunch or wrinkle when you're in the drops. The pocket system uses zeroSeam construction for a clean exterior, while the Triple Ramp Pocket design inside stabilizes contents and adds capacity for bigger loads. An additional zippered side pocket keeps keys and personal items separate from ride essentials. Diffusor valves and a central rear reflective stripe add 360-degree low-light visibility without adding weight or visual bulk.

Design Benefits

1. Sens Air runs cooler than its predecessor — the updated body textile is measurably lighter and more breathable than the previous GTV generation, while retaining the plush next-to-skin feel and full UPF 50+ protection that long sunny rides demand.
2. LouvreTec eliminates fit distractions — strategic darting at the collarbones and across the back removes excess material before it has a chance to bunch, keeping the jersey clean and wrinkle-free whether you're climbing seated or pushing hard on the flats.
3. Pockets that hold their shape under load — the Stabilizer V11 back panel and Triple Ramp Pocket construction work together to prevent sag and lateral movement even when rear pockets are loaded with CO2, gels, and a hydration mix.
4. Separate storage for personal items — the additional zippered side pocket keeps keys and valuables isolated from ride nutrition, which matters on longer efforts where you're digging into pockets repeatedly.
