The next evolution of our hypercooling, ultrabreathable Summer Skin Layer, re-engineered to be more elastic, more breathable, and 15% lighter. The new textile blend creates a more elastic, body-wrapping shape for a better second-skin fit. The textile’s more open structure also increases cooling airflow and breathability, and its permanent odor control doesn’t diminish after washing. The deep collar shape and sleeve lengths mirror the collar shape and sleeve lengths on regularFit endurance jerseys and second-skin racingFit jerseys alike.
