There are many different types of trauma plates with the overall consensus being that trauma plates made from steel offer the best protection. One of the reasons why steel trauma plates offer the best protection is they cannot be punctured by knives like Kevlar trauma plates. This ensures that your vital organs have a front facing layer of hardened steel backed by soft Kevlar in your vest for maximum protection.
The use of blunt force trauma protection plates will help increase the capabilities of your vest. While your Kevlar vest covers the ballistic threats, the blunt force trauma associated with a bullet strike is intense. With the proper use of this trauma plate you will significantly lessen the amount of injuries you would incur from the blunt impact of the bullet strike. Most concealable Kevlar vests feature a 5" x 8" front pocket that will accommodate this plate and once installed you will have the peace of mind that you've taken extra steps for your personal safety.
After reading the other reviews, I thought it might be helpful to include this citation of Trauma Plates from Wiki:
"A trauma plate, also known as a trauma pack, is a plate that is an add-on component/insert to a ballistic vest. Its primary purpose is to absorb and disrupt the kinetic energy of a bullet impact and reduce the blunt trauma transferred to the wearer of the vest. Trauma plates typically enhance the ballistic value (how "bulletproof" it is) of the part of the vest that they are positioned behind."
Those sold here look like they will do the job. I will be ordering additional units...
I don't bother with anything as light as Kevlar since it isn't sharps resistant and where I am, AK is a likely consideration. That said, they are nicely formed trauma plates. If you are using them for anti-sharps, or low angle fire, they will probably serve well. They can also be used to cover the D30 inserts in another offering, http://www.keepshooting.com/french-army-d30-covert-impact-vest.html, to make up inserts for the Osprey MKII PC. I don't recommend them for direct fire, but with proper care and backing, they should do will for incidental fire. I recommend getting more than you think you need. Two is one, one is none.
As you probably expect, this is really just a piece of curved sheet metal. Fortunately, there are no sharp edges, and the plate is uniformly covered in paint to prevent corrosion. It's not quite 1/16" thick, and bows out about 1/2". It happens to fit the trauma plate pocket in my armor almost perfectly, but the curvature is a bit much for my chest. I have no idea how it stands up to bullets.
Good back up for vest, can't beat sale price.
I ordered two. They are exactly as advertised. Seem to be of good quality, hope I never have to put that to the test. They are a little pricey but still considering ordering two more.
The trauma plate is great, put two in your vest for better protection.
Very well made, fairly priced, and a must have for plate carries.
I got some of these off of another site, and they do stop low velocity ammunition.
I bought two to double them up in my vest,good product!
I bought one of these trauma plates with the first vest I bought from Keep Shooting and the other came with my second purchase, for free. They are very nice and of good quality, but I think they are a little pricey. With that said, where else can you get one???
