AR550 III+ Multi-Curve Body Armor Plate Set

Durable Steel Armor Plates Built for Reliable Protection

The AR550 III+ Multi-Curve Body Armor Plate Set is designed for dependable protection, durability, and comfort. Constructed from AR550 steel and featuring an ergonomic multi-curve profile, these plates provide a secure fit while allowing improved mobility during extended wear.

Certified to NIJ STD-0101.06 Level III standards and tested against select special threats including M855, AR550 III+ armor provides trusted protection for law enforcement, security professionals, prepared citizens, and anyone looking for reliable personal defense.

Built for Comfort: Multi-Curve Design

Body armor needs to do more than provide protection — it needs to fit properly.

Unlike flat armor plates, the AR550 III+ Multi-Curve design contours naturally to the body, helping distribute weight and improve comfort during extended use.

Available in multiple sizes and cuts, you can choose the plate configuration that best matches your carrier, coverage needs, and mobility preferences.

PolyShield Fragmentation Protection Coating

Steel armor performance doesn’t stop at the plate itself.

The available PolyShield Fragmentation Protection Coating provides an additional protective layer designed to help reduce fragmentation concerns associated with steel body armor.

Very nice plates

The compound curves on these plates make them comfortable to wear. The coating that is on these is also of great quality.

Most comfortable chest plates on the market

After receiving a referral from a friend and being able to put my hands on his plates, I was introduced to Caliber Armor and decided I would order my next set of plates from them. I appreciated that they are located and manufacture in Kentucky, USA. The proprietary Spaulding protection option they use on their plates is thick and after testing is much more viable than the thin truck bed liner style products that other companies use. It's the real deal. This coupled with their option for multi-curve single press process they use for form fitting their plates make them the most comfortable plates I've worn yet. Highly recommend these plates especially if you have to spend any length of time wearing a carrier.

Worth the investment

Arrived in good fashion and I immediately placed the plates in my carrier. Definitely a heavy set of plates for sure but if in good condition, one can easily adjust to the extra weight.
Hopefully I never have to be in a position to have them tested for ballistic safety but if I do, I trust they'll do a good job.
Very reasonable price for III+ level plates.

Excellent

All steel plates are heavy, but these plates are really beautifully made. The compound curve is dramatically more comfortable than plates. The shooters cut is really nice for movement and shouldering a long gun. And the anti-spall coating is ridiculously beautiful (I am assuming that it is also effective)
On top of all that, the price is better than competitive.
Than you.

Back plate

Almost too perfect of a fit for my plate carrier. I purchase of the 10x12 as to match the front plate. It is a tight fit. This is not necessarily a problem, as it is an observation regarding the plate carrier.

Awesome!!

Absolute superb fit and coverage. I actually traded these out for my ceramic plates. Even though they weigh almost twice as much, they are very comfortable. It makes them feel lighter because the fit is better. The contours allow my whole body to carry the weight.

After watching the video I had to upgrade my gear to these! Great quality and feels great with the shape around the body. They definitely give you more room to breathe over flat plates. Im thankful to have great protection in some of the neighborhoods I patrol. Highly recommended! - Infantry leads the way!

Fantastic

I bought a couple of AR550 plates in SAPI version for my tactical vest. Heavy, strong, durable...COMFORTABLE with the multicurve shape! I was searching for something not expiring after few years and with an high level of protection...and I went through Caliber Amor plates and I'm very happy with them. Moreover, you can also buy them on Switzerland.

Well Built.

I already own a pair of lightweight cut plates from AR500. I figured I'd get a SAPI pair for more coverage. My one ding is that both plates and no magazines come in at 20Pounds. So I went with one lightweight and one SAPI to bring the weight down to about 15pounds.

Incredibly Helpful Staff

The staff assisted me and botified that my current selection would not fit in the plate carrier that I had ordered. They went above and beyond to rectify the situation. I will shop here again.

Caliber curve is perfect

Caliber has got it going on. Best plate curve in the industry. So comfortable and well fitted that you will want to sleep in it. Orders ship same day and they actually answer the phone.. If you are overwhelmed by shopping all the available armor out there as I was. Buy Caliber and rest easy. You will not be disappointed.

Great product

I am very happy and surprised with the shape and comfort of the SAPI multi curve plate. I was skeptical at first with how it would sit in the plate carrier, but the curves of the plate sit nicely in the carrier and do not restrict my movement in any way while wearing it.

Fits great

I have a Crye Precision JPC 2.0, and these plate fit nice and snug. While wearing my plate carrier, I feel much more comfortable than the last set I had. I already told my squad leader that we should get these issued instead of the crap we get. If needed to I would buy another set right away.
