The NRS CO2 Re-Arming Kit lets you re-arm the CO2 inflation device on your NRS Big Kahuna PFD so it's always ready when you need it.

• Includes one 33 gram replacement CO2 cartridge and an arming indicator tab for use with the NRS Big Kahuna PFD.
• If you are flying with your Inflatable PFD, the Transportation Safety Administration (TSA) says on their website, "You may bring a life vest with up to two CO2 cartridges inside, plus two spare cartridges in your carry-on or checked bag." Be aware that individual TSA agents may not have read that particular regulation.
