Make sure the bulletproof vest you are buying is a leading brand. If they do not have a website, they are usually not a top brand. It must stop a bullet! Make sure the armor has an insurance policy and will provide a copy on request. Does your bulletproof vest carry a certification from the NIJ that is available to you. Make sure the carrier of the bulletproof vest is removable so you can wash it and or change carriers. Does the panel that is inside the carrier of the bulletproof vest keep moisture and elements from getting to the ballistic material. Get the facts before you buy any police officers vests for body protection.
