The lineup includes a CLIMACOOL+ singlet, a CLIMACOOL+ jersey concept, a tank, a vest, and the CLIMACOOL System, all aimed at keeping athletes cooler while they push pace. The singlet is framed around maximum airflow and minimal heat, while the vest is pitched for tackling tough conditions and cutting friction. The collection also leans into temperature control, with the system described as handling every degree and supporting prepare, perform, recover routines. It also pushes performance apparel toward more specialized, climate-aware pieces that promise comfort when the tempo and temperature both climb.
