Which rifle rated flexible armor is better Hexar or Dragon Skin?

      As a development engineer for armor systems for 30 plus years now, I always look at designs in an advantage disadvantage sort of way, so I see both systems have their pluses, it just comes down to which one satisfies your requirements best, whether that's cost, thickness, weight, or performance. You can check the PDF SPEC SHEETS page at the top right and read more about Dragon Skin and then decide.

Why is the RZLIIIA so good as compared to other 3-A/HG2 systems on the market?

There are several reasons, 1. we don't design this system around prearranged shot locations to effect BFT (Blunt Force Trauma) for the sole purpose of passing a test specification, and 2. we use 100% SB117, which is a 6 ply 0/90 UDPE Dyneema made by Avient. Although now there is some new generations from Honeywell and Avient, they aren't as stable and as durable as the 6 ply product. We use a non hybrid 100% of a really good material as a concept instead of trying effect BFT or prearranged "Fair Hit" shot locations. We care more about the worst case scenario, and a margin of safety when the fire fight ISN'T fair. We know based on testing that the RZLIIIA will out perform any other 3-A/HG2 armor out there in the 1Lbs/Sq. Ft. or less range.  A lot of times it will out perform much heavier systems as well. 

That's a big claim, how do you know?

Because I personally have been in this business for 36 years, and all the other corporations I have seen that are still here or have come and gone always try to do the same thing, make it pass the test as light as possible, and they always introduce other materials that aren't as high in ballistics to work on the BFT, that are shot in prearranged fair hit locations. That's one of the many faults of the NIJ test protocol.  In the real world, who ever heard of the bad guys making sure their shots are fair???

The test we run is 15 shots in a 5" diameter circle with the threat level small caliber they are supposed to stop, many of these shots will be very close to another, now that's a test, most certified units under those conditions will lose at least few rounds.  When you use the best material, and 100% of it, the ballistics don't lie.

.44 Magnum V-50 - 1769 Ft./Sec

.357 Sig FMC V-50 - 1891 Ft./Sec.

All at .85 Lbs/Sq. Ft. 

A medium-reg concealable panel set weighs a mere 3 Lbs, and is only about .195 inch thick.  

Even if its just one of the best, there is no question about it, it's a great unit, and every customer who has ever bought the RZLIIIA has been happy, its a great product even if it's just one of the best!  Our price is good too!

But my opinion when you add up all the categories and weigh all of them side by side including cost, I do think it's best unit out there,  Lbs for Lbs or by weight, or by cost or all three!
