Premier Body Armor STRATIS IV Enhanced - Multi-curve- Shooters Cut fit all the marks. After reading several reviews watching videos, I made the purchase. I hope I will not need to test these plates out, I am confident I have purchased the right equipment for the right job. you cannot go wrong with STRATIS IV Enhanced - Multi-curve- Shooters Cut.
