Our newest jersey merges our high-performance Nine Trails fabric with a mountain-bike-specific design to keep you comfortable through variable weather and changing altitudes. The soft and supple 4-oz 100% polyester wicks and breathes, and the three-quarter-length sleeves cover the elbows (no gaper gap when you’re wearing pads) while promoting airflow. Articulated, flatlock seams minimize chafing and the longer back hem contours to your body position. On the right hip a small, hidden zippered pocket secures valuables and is accessible while wearing a hydration pack. With Polygiene® permanent odor control.
