Ultimate Comfort

Viper Modular Suspension System

Fully adjustable using the fit-band dial, the Viper helmet retention system and netting is designed to maximize comfort, stability, air circulation, and protection during long periods of wear


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


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

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

Impact Protection

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