Awhile back, DefRev published a story on the Rabintex Attack Helmet, which is currently the lightest IIIa rated combat/tactical helmet in the world. The Attack Helmet is just one example of Israeli technological innovation of late with regard to products with military Spec-Ops and LE SWAT applications.

Well, Rabintex is back, this time with a body armor/ballistic armor product called Knightex. This product was recently introduced at the Milipol Show in Paris. Knightex is an all-aramid, Zylon-free (no Toyobo components) anti-ballistic fiber composite that is stronger and lighter than any aramid composite product that has come before it (at the same protection level).

At 4.2 kilograms per square meter (0.86 pounds per square foot) at 5mm thickness for level IIIa protection (rated to stop high-velocity 9mm NATO ball and certain types of .44 Magnum ammo), Knightex approaches Zylon’s extreme light weight to strength ratio, only without any of…

Zylon’s (or Spectra’s) alleged heat and humidity vulnerabilities or premature integrity degredation problems (as have been portrayed by various sources, including threads on TacticalForums.com–see links below). We received the information on Knightex’s weight and performance from Rabintex officials. Knightex’s light weight is revolutionary for an aramid fiber that "meets and exceeds all progressive standards in the market (e.g. NIJ, SK, IDF etc.)." Just to compare, Rabintex officials informed us that Kevlar comes in at 6 kilograms per square meter. DefRev isn’t sure whether they were referring to Kevlar 129 or KM2.

So, how does Rabintex’s Knightex achieve such impressive performance? Well, DefRev really doesn’t know, because the company is currently extremely tight-lipped about it. Rabintex did, however, share with us that "raw materials are chemically treated in a special way, at the factory.” Knightex is also a hybrid material. DefRev believes one of the aramid components in it is Twaron, but we don’t yet have any proof to back up this theory.

Rabintex also offers an "improved" or "upgraded" Knightex product that weighs 4.6 kilograms per square meter. This “improved/upgraded” Rabintex Knightex product was developed in order to meet the German SK1 standard, and was supplied recently to the German Army (Bundeswehr) for testing. It is DefRev’s understanding that this "upgraded" Knightex product is basically a level IIIa+ product, since it was created to stop the Dynamit Nobel Action 4 9mm round, as well as another German round called the QD-PEP. Both of these bullets, according to reports, are all brass (containing no lead), and only deform minimally at the lips of the hollowpoint.

Rabintex’s primary goal with Knightex, it would appear, is to literally replace every single Zylon-incorporating anti-ballistic protective vest and panel/insert in U.S. military and law enforcement (LE) inventories.

Knightex comes with a 10-year warranty, and is currently patent pending.

DefRev hopes that both the Rabintex Attack Helmet and Knightex body armor products live up to the company’s claims, especially in the long run.

Assuming they do, Rabintex deserves to sell a lot of Knightex.

If you or your organization would like to purchase Knightex body armor or ballistic panels, you can contact Rabintex’s marketing manager, Shachar Bernhard, at [email protected], or Itai Gomer at [email protected]. Yoav Kapah, Rabintex’s technical guru and head of R&D, can be contacted at [email protected]. You can contact Rabintex Industries by phone (they’re located in Israel) at 972-3-5700-196. Remember to dial "011" first, if you’re calling from the U.S.

As DefRev has already mentioned, Knightex is a Zylon-free product.
