Avoid the Coast Guard heckling and lifeguard nagging, get the Quiksilver SUP Inflatable PFD. Simply pull the emergency cord on this little pouch and a USCG approved PFD instantly inflates for your safety. The SUP Inflatable PFD is activated by a replaceable CO2 cartridge that comes with an emergency whistle and a zippered pocket for holding your chapstick, skittles, and your lucky troll doll. What’s wrong with being a little prepared?
