Riddles rock. What wraps snugly around your waist, might save your life, and doesn't even look like an overstuffed fanny pack' It's the Mustang Survival Manually Inflatable Belt Pack PFD. This little number wraps around your waist and stays in place with a snappy plastic buckle. When you pull the activation tab, a bright yellow PFD pops out and blows up to offer a whopping 35 pounds of buoyancy. You'll fit right in when you wear the Inflatable Belt Pack at your stand up paddleboard lesson or while you're wade fishing. It's not designed for high speed, high impact water activities though, so you'll need a different PFD for your flaming water ski routine for the Fourth of July. When your SUP gets flippant and you get wet, you have decisions to make pull the activation tab and put the PFD on while it's inflated or simply remove the yellow bladder, put it on while it's flat, and then inflate it. The only wrong choice is not wearing a PFD at all. If you're in the water for hours on end, the PFD might start to flag. Pop the blow up tube in your kisser and put your hot air to work. The belt is backed with Mustang Survival's proprietary neoprene Comfort Lining, and it's designed to conform to the contours of your body. Extra safety features abound to help you get found: a whistle, SOLAS reflective tape, and reflective piping. After blowing things out of proportion as in, inflating the PFD, you need to re arm the belt pack before you can use it again. Just follow the instructions for testing and re arming your PFD re arm kit sold separately.
