Adjusting the Chest Strap
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 ends
of the straps. 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 adjustment D-rings until the BC fits comfortably.
The chest strap also has two vertical positions. To adjust, slide the strap
(up or down) across the small “ bumps” on the strap guides (Fig. 9).
