The Half Zip Jacket is a performance-oriented outerwear layer that is designed for running or outdoor workouts in chillier weather. The body is crafted of an innovative quick-dry ribbed poly that helps to both retain and regulate heat with its usage of COOLEVER™ yarns, a high-performance fiber that draws out moisture and dissipates heat quickly due to its irregular-shaped cross section. We also designed underarm inserts that feature an anti-microbial jacquard mesh that helps to keep you cool. On a cool fall day, we recommend using the Half Zip as your top layer and when it's colder out, you can pair it with our Trail Jacket or Asymmetrical Fleece Pullover for added warmth and wind protection. A subtle tonal rubber logo bar is sewn into the wearer's left hip.
