Tips

To get the perfect fit, adjust the sternum straps while wearing the vest with your typical race load. The soft flasks can be filled and slid into the front pockets; the straws route over the shoulders for easy sipping. For colder weather, the back sleeve can hold an insulated bladder to keep water from freezing. When not using poles, the Quick Link system tucks away cleanly. Always rinse the vest after sweaty runs and hang to dry away from direct sunlight to extend its life.
