What Our Gearhead(R) Experts Are Saying: "I've used this jersey on sweltering 90-degree days, and the AirCell fabric is a game changer. It feels almost weightless once you're moving, and the Push Pull sleeves give you that supportive, race-inspired feel without being tight. It's cool, breathable, and stable even with full pockets-easily one of my go-tos for hot endurance rides." We love how the Assos MILLE GT Jersey S11 EVO maximizes airflow and cool comfort for long, hot days in the saddle. Its new AirCell fabric uses an open-hex knit to pull air through the jersey the moment we start pedaling, keeping us dry and steady even during steep climbs and slow, grinding efforts. The GT fit stays comfortable without feeling loose, striking that perfect balance for high-mileage riding. Stabilizer V11 mesh reinforces the pocket panel without adding heat, giving us secure structure for tools, food, and essentials. Push Pull sleeves-borrowed from Assos' racing platform-wrap the arms in lightweight, UPF 50+ elasticity, delivering stable support without pressure points. When temperatures climb and the day stretches long, this jersey keeps airflow high and discomfort low.
