Protect your torso against accidental and violent threats with this C.P.E. vest made for demanding professional use! Designed for covert wear under your regular clothes.

The C.P.E. Diamond NIJ IIIA weighs only 1.8 kg (3.97 lbs) in size Large. The panels are less than 5 mm thick (0.2"), yet offers excellent multiple hits protection and hits close to the edge of the panel. Each protective layer is separately laminated for improved hygiene and moisture protection. The panel offers the best possible protection with minimal trauma.

The protective panels are stiff and stand upright on their own. The initial feeling is slightly cumbersome, but the vest adapts to the wearer soon after donning it. With a well-protected body, the mind is at ease and the user can focus on the task at hand.

Protection level NIJ IIIA

The IIIA level according to NIJ-standard is pretty much the lowest used in military and LE applications these days, but also the highest level that can be achieved with soft materials. NIJ IIIA is commonly used in bullet-resistant vests worn underneath clothing as well as flak vests.

NIJ IIIA stops the following threats (list not exhaustive):

  • .22LR (rimfire pistols and rifles)
  • .44 Magnum SJHP
  • 9x19mm FMJ (pistols and submachine guns)
  • Fragmentation and ricochets.

Size info

The vest is designed to be worn over an undershirt below all other clothes. The fit is tight. Don't choose a too large size: it may be loose on you or restrict movement. Especially a shorter person should not pick a tall vest: the bottom edge of the panel may hit your thighs and the top can dig into your throat.

When reading the table, focus on being in the right range around the chest and ensure you're tall enough. If you're between two sizes, pick the one with the more suitable length.

I would recommend for a friend

Comfortable wear, simple to put on. Comes with a functional undershirt, too.
Will report back if I get shot while wearing it, provided it did its job.

Got one a while ago while it was still allowed to ship to my country, I wonder what nonsense the powers that be over here used as an excuse to forbit me from ordering one online. If it works I don't know, still need to test it but it's not as uncomfortable as one might think and you guys might want to add a photo of someone wearing this vest under a sweater or something because you don't see the vest unless you know to look for it
