Engineered with lightweight, breathable fabric, this technical tee offers UPF 50+ sun protection and ActiveFresh™ odor control to keep you cool through extended activity. The quick-drying, moisture-wicking construction manages sweat, while the chafe-free design and dynamic reach patterning move naturally with you.
