When you expect conditions on the trail to change from sunny to rainy to slightly cool, have a shirt that adjusts with you. The Trailhead does just that through every aspect of its construction. First, quick-dry Supplex material moves moisture away from your skin, so you always stay comfortable, and keeps your perspiration in check. Then, while vents and mesh improve airflow, you can vary coverage for your arms with the roll-up sleeves. Thus, this shirt’s equally apt for hiking on a cool fall day as it is for exploring in the middle of summer.
