Introducing the Gentex® LX9 Liner System, An Affordable, Drop-In Liner Upgrade for US Military Combat Helmets

CARBONDALE, PA, June 2, 2025 – Gentex Corporation is pleased to announce the Gentex LX9^™ Liner System, available now. This drop-in replacement liner is compatible with a broad range of commonly used ground combat helmets and is optimized for comfort and stability in a lightweight package. As part of its adoption, Gentex will deliver over 18,000 systems to the US Army for use in the NG-IHPS helmet system in 2025.

“Our LX9 Liner System gives users a lightweight, high-performance upgrade to instantly increase in-use comfort,” said Kevin Reilly, Segment Director of Close Combat at Gentex Corporation. “The customizable and configurable design allows for the end user to tailor the fit to maximize airflow and reduce hotspots.”

The system is designed to provide unmatched comfort for ground combat helmets, including ACH, ECH, and NG-IHPS models. Featuring advanced breathability and absorbency, it includes a 9-piece EPP and comfort foam pad set, which includes a redesigned brow pad for added stability. Its customizable, one-size-fits-all design allows for easy adjustments using existing hook-and-loop mounting locations in the helmet shell. This enhances airflow, reduces hot spots commonly found in today’s standard issue 7-pad system, and better accommodates headband-mounted communication systems. Lightweight, durable, and adaptable, it ensures optimal fit and comfort for users in demanding environments.

At under 66 grams, the LX9 Liner System is the lightest liner option on the market today, reducing overall head system weight while maintaining needed impact protection. It has been developed to provide impact protection exceeding AR/PD 10-02 in a wide variety of common helmets.
