A body-mapped technical top that’s ideal for running, hiking, and other active adventures, the Fluid Zone Long Sleeve Zip is a highly breathable merino layer that lives for days in motion. This slim-fit active top features a full-zip design and a soft, breathable and stretchy blend of merino wool and LYCRA®. In strategic areas on the back and under the arms, we used lightweight merino eyelet mesh to amplify ventilation and improve airflow when you’re on the move. Flatlock seams throughout eliminate chafing, and zippered hand pockets secure your small items on the trail.
