Trail running sparked the Cormac’s design and it quickly became a go-to piece for any high output activity where comfort and climate control are essential. The lightweight Ostria™ fabric provides UPF 50+ sun protection, performance stretch and soft comfort. Its gridded construction helps speed moisture transfer and the fit and patterning encourage airflow. Long sleeves and the tall collar extend the sun protection and the deep V-neck unzips quickly for ventilation.
