Like most safety equipment, it is almost always a 'yes' depending on what material the jacket is made from. Foam can last for 10 years if no damage to its straps, buckles or covering material. Hybrid jackets and gas jackets need to be serviced regularly in order for any issues to develop. However, they also have a theoretical life expectancy of 10 years. Although service intervals may differ by manufacturer, the minimum recommended maintenance should be at least every two years. To ensure that service records remain current, many jackets of high quality will come with a service interval disc.
