The Fox Flexair Ascent Short-Sleeve Jersey is designed to help us stay cool, dry, and comfortable on long climbs and fast descents. The Polartec Delta front panel actively helps to keep us cool by dispersing moisture and increasing airflow. We like that this jersey's slim fit and lightweight feel give us full freedom of movement while zipping down the trail. On those days when we don't want spandex and we don't need tough fabric for protection, we reach for the Flexair Ascent Short-Sleeve Jersey.
