Gentex Recommended replacement schedule

Maintain the protection and performance levels of your Gentex/ALPHA helmet system and extend its use by replacing worn out components and assemblies with genuine Gentex/ALPHA replacement parts, available for all of our fielded systems. Over time, parts can become worn, warped or otherwise damaged, which diminishes the protection capability of the helmet system. Based on decades of usage experience, Gentex recommends replacing protection-critical components and assemblies of the helmet system at regular intervals.

Please find the recommended replacement intervals below for the various helmet and mask components.
