The ultimate choice for SUP paddlers! So compact, you'll almost forget you're wearing it. Yet pull the cord and whoosh! The CO2 cartridge immediately activates and a life jacket bursts out of the pouch. Just put it on over your head, it is tethered to the belt pack around your waist so it won't float away. Fold lines for easy repacking of the bladder. Soft polyester shell with single point indicator window to confirm its readiness. GREEN means GO - it's a PFD on demand!
