We give a shelf life of five years for the inflators and ten years for the electronics unit. During this time, the backpack can be used without hesitation. Even after a deployment, the airbag fabric can be checked independently for damage and does not need to be sent in for maintenance. After the specified number of years since the date of manufacture, we can check the electronics. We will replace the inflator free of charge if you do not have a deployment within this period.

This means you can use the backpack for a lifetime.
