Extra-Chest Strap
 

 
 This is an additional chest strap. Having two chest straps allows the load on the chest to be distributed more evenly, providing greater stability when carrying the backpack. The increased freedom of movement around the waist allows for easier access to jacket pockets and reduces interference with climbing harnesses, etc.
