Here at Nutcase we recommend replacing a helmet every three to five (3-5) years depending on use and handling. This is based on many factors such as the age of the helmet, the wear over time including impacts or drops to the ground, weather or heat exposure, handling, the potential for degradation from personal care products like sunscreen or bug spray, and the simple fact that helmets do improve over time.
While Nutcase helmets kept in good condition can be suitable for use beyond the 3-5 year recommended lifespan, it’s also true that they can degrade over time. This is why Nutcase recommends replacing the helmet within this 3-5 year timespan.
If you have experienced a fall and and your Nutcase helmet experiences an impacted, you should have the helmet inspected or replace the helmet immediately, even if no damage is visible. The reason is that helmet liners are designed to absorb energy from impacts and they do this through their own degradation or destruction – similar to an airbag in a car. Just like a deployed airbag, the liner could be compromised from an impact and in most cases the helmet may not provide the full protective capability it was intended for.
