Galvion Batlskin Viper P4 Ballistic Helmet

The Galvion Batlskin Viper P4 is a UHMWPE advanced combat helmet designed to exceed U.S. military specifications for ballistic threats, blunt impact, and blast fragmentation, while weighing up to 24% less than the legacy U.S. Army ACH. Available in Black and Tan499, in Medium, Large, and X-Large, each configured with a High cut, Viper Front Mount, and Interlocking Long Rails.

Built on a Generation of ACH Advancement

The Batlskin Viper P4 represents the first significant advancement in Advanced Combat Helmet technology in 15 years. Galvion rebuilt the ACH concept around UHMWPE composite construction, a material choice that allows the shell to meet or exceed U.S. military ballistic, blunt-impact, and blast-fragmentation specifications without carrying the weight penalty of earlier designs. For a wearer spending hours in the field, that difference compounds: less fatigue at the neck and shoulders, more sustained attention on the task.

Weight Reduction Without Protection Trade-Offs

At up to 24% lighter than the legacy U.S. Army ACH, the Viper P4 shell achieves its weight reduction through advanced composite shell technology rather than by thinning coverage or narrowing the protection envelope. The Medium and Large variants come in at 3.92 lb; the X-Large at 4.18 lb. For personnel who wear a helmet through extended operations or training rotations, the reduction in cumulative load matters as much as any single-session comfort feature.

Ready for Accessories Out of the Box

Every Viper P4 variant ships with a Viper Front Mount and Interlocking Long Rails already installed. The front mount accepts standard NVG shroud-compatible devices, and the long rails provide continuous mounting surface along the helmet's sides for lights, cameras, and other rail-mounted accessories. No aftermarket hardware or drilling is required for basic accessory integration. The High cut profile keeps the ears clear for communication headsets and hearing protection.

Who This Is For and Isn't

The Batlskin Viper P4 suits military personnel, law enforcement operators, and serious tactical professionals who need a high-cut ballistic helmet that meets or exceeds U.S. military protection specifications while reducing neck and shoulder fatigue over extended wear. The included front mount and long rails make it ready for NVG and accessory integration without additional hardware.

No specific NIJ certification level is stated for the Viper P4; buyers who require a helmet with a confirmed, independently certified NIJ rating should verify current certification status before purchase. The High cut profile does not extend over the lower ear or jaw. This helmet provides no mandible or face coverage. It is not a bump helmet and is not intended for non-ballistic applications where a lighter, uncertified shell would suffice.

Common Questions

What does "exceeds U.S. military specifications" mean for ballistic protection?

The Batlskin Viper P4's UHMWPE shell meets and exceeds U.S. military specifications for ballistic threats, blunt impact, and blast fragmentation. No specific NIJ certification level or CPL listing number is stated for this helmet. Buyers with a requirement for a confirmed NIJ-certified rating should verify current certification status independently before purchase.

How much lighter is the Viper P4 compared to a standard ACH?

The Batlskin Viper P4 is up to 24% lighter than the legacy U.S. Army Advanced Combat Helmet, achieved through UHMWPE advanced composite shell construction. The Medium and Large shells weigh 3.92 lb each; the X-Large shell weighs 4.18 lb. Actual weight savings relative to a specific legacy helmet will vary by size.

What accessories come included with the Viper P4?

Every Batlskin Viper P4 variant includes a Viper Front Mount and Interlocking Long Rails. The front mount is compatible with standard NVG shroud-style devices. The long rails run along the sides of the helmet and accept standard rail-mounted accessories such as lights and cameras. No additional mounting hardware is required for basic accessory integration.

Does the High cut profile work with communication headsets?

Yes. The Batlskin Viper P4's High cut profile is designed to keep the ears clear, which allows the helmet to be worn alongside over-ear communication headsets and hearing protection devices. The cut does not extend down over the ear, so standard tactical comms equipment fits without modification to the helmet.

Can the Viper P4 ship to my state?

The Galvion Batlskin Viper P4 is a ballistic helmet and is subject to body armor shipping restrictions. It cannot be shipped to New York or Connecticut due to state body armor laws. It is also subject to U.S. export regulations. Under 18 U.S.C. § 931, anyone with a federal felony conviction for a crime of violence is prohibited from purchasing or possessing body armor.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
