Turtleskin Metal flex armor KR3-SP3 are special cut- resistant protective panels constructed according to a new patented technology of small metal plates that can offer a fairly high knife, spike and needle protection (NIJ levels 2 and 3). For the time were already 40,000 Dutch policemen equipped with such Metal Flex armor panels.
A Turtle Skin Flex Armor panel is not a "stand alone" panel, It must be supported with a soft ballisitc packet to achieve offical KR3-SP3 certificat. These panels can be used as cut and stab resistant to upgrade existing body armor NIJ-3A(04) / NIJ-3A(06) with a cut-resistant layer.
The Flex armor panel can also separately in a carrying pouch be worn as high stab and spike resistant protection.
This cut and puncture resistant panel is the protection value KR3-SP3.
