Superior Comfort & Fit

  • Engineered to comfortably fit a wide range of head shapes and sizes - adjustable liner and suspension system is optimized for impact protection, comfort, and extended-wear.

One-handed Adjustment

  • Tighten or loosen the dial fit band and comfort pads around the circumference of the head with a simple turn of the dial fit ratchet mechanism.


  • The 4-point retention system has a height-adjustable nape pad to further stabilize the system when using NVGs.

Impact Protection

  • Impact liner is made of durable, low-profile material that exceeds U.S. Army ACH impact standards.

Ventilation and Cooling

  • An adjustable crown net wicks perspiration and suspends the helmet shell on the wearer's head for freer air-flow and circulation.
