Revision's Batlskin Viper P4 Premium Combat Helmet, built in the ACH shape and to exacting military specifications

REVISION HAS MODERNIZED THE TRADITIONAL ADVANCED COMBAT HELMET: The Viper P4 Head Protection System brings this essential equipment in line with today’s technological advances in warfighter’s equipment. Utilizing cutting-edge, composite, hybridized Ultra-High-Molecular-Weight Polyethylene (UHMWPE) material, Revision manufactures the most advanced combat helmet that is up to 24%* lighter than the legacy U.S. Army ACH system, pushing the boundaries of obtainable weight reduction while maintaining superior ballistic and fragmentation protection. 

The Batlskin Viper P4 Lightweight Combat Helmet is the foundation for all Batlskin modular components, including the Front Mount, Rails, Mandible Guard and Visor. Helmets are available in a full range of cuts (full, mid and high), sizes (small to x-large) and colors. They come standard with one NVG hole and the Modular Suspension System.
