ADJUSTING THE RAIL SYSTEM
The chest strap fits across your sternum and keeps the two shoulders from slipping to the sides, ensuring a
comfortable and secure fit. Before donning the BC, loosen and disconnect the chest strap. After donning the
BC, connect the chest strap and tighten by pulling on the free end of the strap. The chest strap should feel
comfortable across the chest; it should not be overtightened so that it feels restrictive. Once the shoulder straps
are in position, adjust the shoulder strap length by pulling down on the torso straps until the BC fits comfortably.
The chest strap is on an adjustable rail system. Adjust the chest strap up or down on the rail system by pushing
in on the spring release, slide the chest strap to the desired position and release the spring to lock in place.
