The men's Nike ACG "Wolf Tree" Jacket is made of 100% polyester Polartec fleece that offers lightweight warmth and breathable comfort. The ultrasoft fabric retains body heat while allowing moisture to escape, ensuring dryness during changing weather conditions. It features a classic fit for easy layering, a two-way zipper for adjustable ventilation, and elastic thumb loops for secure sleeve placement during active movement. Zippered pockets safely stow small essentials, and its lightweight construction makes it perfect for extended trail activities.
