The four-way-stretch fabric not only moves with you, it has been treated with a variety of highly technical finishes to keep you dry and comfortable. Wicking, quick-drying and cooling treatments efficiently pull moisture from the body, encourage evaporation and intelligently redistribute heat to manage temperature. A premium antibacterial finish offers enduring freshness, and built-in UV protection helps prevent damage from the sun's harmful rays. Ruched details on the sleeves bring texture and style to this powerful half-zip.
