Protective Ballistic Materials

The bulletproof garments and accessories offered by Sentinel Tailors to its clients provides the highest possible level of ballistic protection in the form of a product that is very comfortable to wear and ensures personal convenience and ergonomics. The hi-tech materials used in production qualify as soft ballistic body armor: flexible, non-woven aramid fibers representing the state of the art in protective clothing technology and offering a unique combination of mechanical characteristics, chemical resistance, excellent durability, and thermal stability. Only hard ballistic armor offers a higher level of protection: rigid plates made from e.g. steel or ceramics which are used by military and police forces, in armoring vehicles, and in protection against fragmentation grenades. However, these materials are not suitable for daily comfortable wear, let alone for discreet use and concealment from others.

In order to gain an understanding for the principles by which these materials work, one needs to realize that the most important task in ensuring top-level protection is not to stop the projectile from penetrating through the ballistic armor plate! The kinetic energy absorbed by the plate causes a trauma which in many cases has absolutely devastating effects on the human body. It may lead to fractures, rupture of soft parts, subsequent internal bleeding, and death - even in the absence of a projectile. For this reason, all armor plates produced by us are furnished with an anti-trauma layer and cushioning foam on the side closer to the body. This step adds some negligible weight to the armor but at the same time significantly reduces the effect of the said trauma.

The levels of ballistic protection are defined in various national standards. There is currently no global standard, nor is it likely that such a standard will come into existence in the foreseeable future.

In the bullet-resistant plates and accessories developed by Sentinel Tailors, materials are used (and combined in ways) which comply with the three national standards that we consider to be of relevance:

  • US Standard NIJ 0101.04 (USA)
  • Russia-GOST R 50744-95 (Russia)
  • ČSN 39 5360 (Czech Republic)

In line with these standards, we offer three levels of ballistic protection:

  • IIA (the lowest)
  • II (medium performance)
  • IIIA (the highest)

What follows is a more detailed description of these levels:

IIA
According to our definitions, this is the lowest level or class of protection, offering protection against 9mm handguns and ammunition, and e.g. the .40 Smith & Wesson with low muzzle velocity. With a view to the weaponry in use in today's environment, this protection is inadequate. However, it all depends on the environment within which the ballistic panels are integrated, as weapons and ammunition differ from territory to territory. Incidentally, this level also provides sufficient protection against pneumatic weapons, which are very widespread and may in occasional cases be lethal.

II
We define this as a level affording medium protection. It provides protection against 9mm handguns and ammunition, and e.g. the .357 Magnum with higher muzzle velocity. These types of weapon and ammunition are in most widespread use today, and may be encountered practically anywhere around the globe. This level of protection is very popular and effective. However, it all depends on the environment within which the ballistic panels are integrated, as weapons and ammunition differ from territory to territory. Incidentally, this level also provides sufficient protection against pneumatic weapons, which are very widespread and may in occasional cases be lethal.

IIIA a GOST R 50744-95
This is our definition of top-level protection. Thus certified products protect their wearer against most 9 mm handguns and standard (but not special) ammunition, and e.g. the high-velocity .44 Magnum, shotguns (scatter guns), and automatic 9mm weapons. This level is recommended to ensure full compatibility with various global environments, weaponry, and ammunition. It represents the highest attainable protection in the soft body armor segment.
