Helite CO2 cartridges are easy to replace and simple to use. You can recondition the system yourself in just a few minutes, without any assistance from an authorized person. In the event of a fall, replace the empty Helite CO2 cartridge with a new one of the same size. The size of the cartridge is in proportion to the size of the Helite airbag. It is important to only use Helite CO2 cartridges with our airbags. Helite cartridges have a 10-year guarantee and no expiration date. A cartridge is always included with the purchase of an airbag vest. We recommend that you always have an extra cartridge on hand. For the correct cartridge size, please refer to the size chart. BE CAREFUL of sellers who offer CO2 cartridges that are supposedly compatible with Helite airbags. These cartridges are dangerous for several reasons:

• Technical compatibility problems (gas volume, screw thread etc.)
• Inferior quality to Helite cartridges (tightness, corrosion, fragility, etc.)
• Loss of CE certification and warranty
• Airbag operation is not guaranteed
