The Gentex LX9™ Liner System is a drop-in helmet upgrade designed to elevate comfort and performance for military users. Compatible with ACH, ECH, and NG-IHPS helmets, it features a nine-piece padding set and redesigned brow pad to ensure a stable and cool fit. Gentex plans to supply over 18,000 of these systems to the US Army in 2025 as part of the NG-IHPS program. Its customizable one-size design uses existing Velcro mounts for easy adjustment, significantly improving breathability and reducing pressure points under long-use conditions, especially with headsets and communication gear.
