As our ultimate endurance jersey for the hottest conditions, weighs 25% less than the standard MILLE GT C2 EVO jersey. The body is engineered with two new, ultralight textiles for breathability and cooling airflow that rival the EQUIPE RS while maintaining the GT’s comfort-tuned fit. The sleeves are also updated, using the same textile as the previous EQUIPE RS Jersey for ultrabreathable, muscle-wrapping support that’s inspired by racing equipment but shaped for streamlined comfort (UPF 15) is so lightweight, breathable, and cooling, that we recommend wearing sunscreen beneath it.
