When you need that extra flotation on bigger water or if you just need extra assurance of buoyancy then check out the Add-a-Buoy air bladder for Stohlquist's Descent PFD. This hardcore rescue vest gets an additional 5 pounds of buoyancy when the bladder is inflated. Without inflation, the Add-a-Buoy lays flat against the backside of the Descent front pocket compartment. Once positioned, the inflation hose valve lays equipped to use at the bottom of a special garage compartment. Ready to use when you need that extra flotation.
