It's pretty understandable why most rafting companies rent out the NRS Big Water V Youth Personal Flotation Device. Not only is it a high flotation jacket for serious waters, but the Big Water also provides a universal fit for most children. Six side adjustments and two shoulder adjustments secure them in this vest while they're careening down wild waters. As a type V life jacket, the Big Water PFD delivers a whopping 17 pounds of flotation for floating.... well, big waters.
