Tips

For optimal comfort, adjust the chest straps so the vest sits snugly without restricting breathing. Fill the soft flasks and place them in the front pockets before putting on the vest to balance the load. If you prefer a reservoir, insert it into the internal sleeve and route the hose through the designated port. After sweaty runs, rinse the vest and flasks with mild soap and air dry to keep them fresh.
