BCs that feature the i3 are also equipped with Flat E-Valve Technology. To deflate the BC, manually pull on the knob and cord assembly located on the right front shoulder to quickly dump air.
CAUTION: In order to dump air as quickly as possible, always use the dump valve at the highest point in the water column. Deflation via the Flat E-Valve located on the upper right shoulder is only effective when in the horizontal or head up position.
