Mens TEMPO! T-Shirt is developed for running in heat, sun and high-intensity conditions. An ultra-light performance T-shirt made from a FUSION-specific Italian fabric with ceramic yarns, combining low weight, high wicking performance and a moisture-activated cooling effect. The hydrophilic fabric is designed to attract and spread moisture through the textile. When the T-shirt becomes wet from sweat or water, the larger wet surface helps evaporation work more efficiently, drawing heat away from the body. This creates an actively cooling effect for up to 30 minutes, depending on temperature, humidity and airflow around the body. The fabric has been tested to UPF 50+, making the T-shirt especially relevant for training and racing in warm conditions with direct sun exposure. The same material technology is used in selected triathlon and cycling products developed for extreme heat conditions, including races such as Ironman World Championship in Hawaii and the Tour de France. Here, it has been translated into a lightweight running T-shirt for long runs, tempo sessions, intervals and races in warm weather. The fit is athletic and stretchy, with low weight, high moisture transport and freedom of movement throughout the run.
