Mille GT Jersey S11 Boss x Assos - Black

Equal parts BOSS elegance and ASSOS engineering, the S11 Monogram is a technical, elegant solution for the hottest conditions. 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, and it weighs 25% less than the standard GT C2 EVO jersey. The sleeves are also updated with trickledown technology from the Racing Series, providing ultrabreathable, muscle-wrapping support inspired by racing equipment but shaped for streamlined comfort. The Jersey S11 Monogram is so lightweight, breathable, and cooling that we recommend wearing sunscreen beneath it.
