What Our Gearhead(R) Experts Are Saying: "I've ridden in this long-sleeve on brutally hot days, and the cooling effect is unreal. AirCell feels weightless once you're moving, and the Push Pull sleeves fit like a second skin with zero restriction. Even with the extra coverage, it breathes better than most short-sleeves. It's my go-to when I want sun protection without overheating." We love how the Assos MILLE GT LS Jersey S11 EVO takes hot-weather endurance rides to the next level with featherlight materials and incredible airflow. Built with the new AirCell fabric, the jersey channels cooling air through its open-hex knit, creating a breathable, ultralight shell that keeps us focused on smooth cadence rather than heat. Stabilizer V11 mesh reinforces the rear pocket panel without adding weight, creating lift-free stability even when fully loaded with snacks and tools. The long sleeves use Push Pull fabric borrowed from Assos' race platform, offering supportive elasticity, UPF 50+ protection, and a sleek, low-volume fit that feels fast and comfortable. When warm rides stretch from sunrise to late afternoon, this jersey delivers the airflow, structure, and comfort we need for big mileage.
