When we designed the UYN Coolboost jersey we wanted it to be not only highly breathable, but also able to regulate body temperature during the activity and to give an immediate sense of freshness from the first moment you wear it. T-Hexagon technology has allowed us to structure the fabric so as to create highly breathable areas and isolation zones based on a scientific mapping of the heat in the human body. Shoulders and sleeves are made from a single piece of fabric thanks to the Hypermotion system: there are no seams that can restrict movement or create irritation. Compress-Waves in the shoulder area support the muscles, improve blood circulation and create a dynamic and attractive style.
