"Mammal" Fast Helmet - NIJ IIIA Protection

The #1 FAST helmet for law enforcement, military, and private security.

The Mammal Helmet is the only all-day solution for special operations forces worldwide. The ultra-lightweight NIJ IIIA bulletproof shell weighs in at only 2.2 lbs. 

A high-cut shell acts as a control center for your communications device, flashlights, cameras, NVG, battery packs, signalers, and any rail-mountable accessory.

Significantly lighter than PASGT, MICH, and ECH helmets while offering the same high-level protection against ballistics and shrapnel.

  • Bulletproof - Constructed from next-generation UHMWPE (Ultra-high molecular weight polyethylene) to provide the same NIJ IIIA protection as Kevlar while reducing the weight dramatically. Resists shotgun slugs, 9mm, .44 mag, .40 cal, and other lesser ammunition.
  • All-day field comfort - Choose between the TW or OC liner system, the best systems in the market. Route cables from side rail between liner channels.
  • Fits most heads - Adjustable dials tighten and conform to any head shape or size giving you a zero wobble helmet system. Your head and helmet system become one unit, feel true weightlessness.
  • Ultra-lightweight - Weighs in at 2.866 lbs. Ideal for multi-day operations. The lightest helmet ever made with zero compromises on safety.
  • Comm Systems - High ear cuts allow you to adapt any communication system to the side rails.
  • Skeleton Shroud - Forged aluminum shroud mounts any NVG and comes with safety shock cords
  • Velcro loop kit - Pre-installed. Mount any third-party accessory.
  • Comfortable fit- The 4-point adjustable straps makes this helmet feel like one unit with your head movements with zero wobble or play.
Suspension/Retention Systems:
Retrofitted Team Wendy system
  • The highest-rated liner and retention system in the market installed onto the Mammal. The TW EPIC Air liner system features a 1/2" thick impact liner with integrated air channels. It is the absolute best liner system for ground combat and is compatible with all communication headsets.
  • 4-point clockwise cable-dialing suspension system.
  • 2 layer padding design offers maximum comfort and stabilization.
  • Full helmet setup with TW retention system weighs in only at 2.866 lbs.

Customer's Love Us

It's no secret why...

I have at least 30 hours under the Limitless Airframe with my PVS-14 NVG. This is without a doubt the best investment if you're gonna run a night vision or camera and battery pack.

I ran JC in Operation Jackal and I did not regret it for one second. The entire weekend, two-day event, I didn't have any head fatigue at all. The memory foam padding is a world of difference. I compare it to a Team Wendy Helmet.

I got to say it's probably the best reproduction of the Crye Airframe, if not, actually one of the best helmets i've ever used just due to its' overall quality.
