What Our Gearhead(R) Experts Are Saying: "I wore this jersey through a week of 95-degree training rides, and the difference in airflow is unreal. The AirCell fabric practically disappears once you're moving, and the Push Pull sleeves feel supportive without squeezing. It's definitely a 'sunscreen required' jersey, but for sweltering climbs and long endurance days, I've never found anything this cool or this comfortable." We love how the Assos UMA GT Jersey S11 EVO transforms blazing-hot rides into flowing, breathable miles. Assos reengineered this jersey from the ground up using AirCell, an ultralight fabric with an airy hexagonal knit that pulls in cooling airflow the moment we roll out. Even under direct sun, it feels weightless and responsive, wrapping us in stretch that supports without restricting. Stabilizer V11 mesh reinforces the rear pockets for structure without adding heat, while Push Pull sleeves-shared with Assos' race-driven DYORA RS line-deliver sleek elasticity and UPF 50+ protection. The result is a super-light, super-cool endurance jersey that keeps us comfortable when summer rides demand every ounce of breathability.
