WHAT NIJ LEVEL IS BEST FOR ME?
This is highly subjective, and the answer is different for many people. Some things to keep in mind: Select armor designed to defeat ammunition used in your own firearm or in weapons known to be used in the area you patrol; know if your armor will be used as part of an active shooter / bug out kit (infrequent wear) or worn for extended periods or during patrols (more frequent wear) ; know what firearms are used by your workforce; be aware of sport shooting or hunting in your area.

WHAT CARRIER WILL FIT MY PLATES?
Most plate carriers are designed to fit SAPI cut plates, and are sized to the plate. For example, a Medium plate carrier from most brands means it will fit Medium SAPI plates. This isn't always the case, but it's the most common way of sizing plate carriers. Small or Medium carriers can generally can hold Large 10x12" Shooter cut plates too, as the dimensions are similar. Each plate carrier is slightly different, so see the size chart on the item page for the best description of the fit.
