The SEAVER gas cartridges are screwed onto the SAFEFIT vests. These cartridges allow the vest to inflate in the event of a fall, thus absorbing the shock and protecting you.
The SAFEFIT vest must not be used without a gas cartridge. Only a gas cartridge suitable for your SAFEFIT vest can guarantee optimal protection in the event of the airbag mechanism being triggered.
