Worn around a paddler&';s waist, the NRS Zephyr Inflatable PFD is the perfect alternative to traditional life jackets for flatwater or near-shore stand-up paddling. a This lightweight self-inflating PFD provides 27.8 lbs. of flotation and only meets U.S. Coast Guard requirements as a Type III lifejacket when worn. (See Note below.) a The Zephyr is stored in a compact, adjustable ripstop nylon waist pack that stays out of your way for SUP, surfing or wading. a In the event of a swim, simply rotate the belt until the chamber faces forward, pull the red tab to inflate with pressurized CO2 and secure the inflated PFD over your head. a Adjustment straps on the inflated PFD allow for a customized fit. a Waist belt features a zippered stretch pocket with internal tether for keys or a whistle. a Also features a manual back-up valve, reflective accents and two D-ring attachment points. a A 24 gram CO2 cartridge comes with the Zephyr. It will simply need to be screwed in to initially arm the PFD. Replacement CO2 Re-Arming Kits are sold separately. a CO2 cartridges are one-time-use only. It&';s good practice to keep an extra CO2 cartridge on hand to re-arm the PFD after each inflation.
