Plate Backer on Carrier
SAPI Cut Plate Backer on Carrier

Plate backers are a great way to add some padding behind your plate, level up a plate rating or even to just use it as a soft armor solution.  All our backers are compliant to an NIJ Level III-A  (How To Choose The Right Body Armor).

The backers can be made in most sizes and can be requested custom if needed although most carriers will accept the Shooters Cut or SAPI cut and it will comfortably fit behind your plate.

Each backer is Sonobonded, which is a sonic seal, on a specific fabric that makes sure that the seal is air tight which means no debris or water can get in which will allow your backer to last.

Made 100% in the USA from USA sourced materials by our team in Knoxville, TN!

  1. Item is first-class in construction. After some issues in shipment time, Midwest Armor came through. I certainly have no complaints about their customer service.
