Inspired by runners, then refined to offer the versatility to handle a wide range of high-output mountain activities, the Cormac is designed for performance, sun protection, and comfort. Its 100% recycled Phasic™ LT fabric wicks moisture, breathes, provides UPF 40+ protection, and is treated for odour resistance.
