This concealable body armor takes proven Level II and IIIA ballistic packages and makes them much easier and faster to order, right off the rack. Thin Blue Line is offered in standard sizes (S, M, L, XL, and up) allowing quicker delivery time to people who need ballistic protection, and can't afford to wait. The Thin Blue Line series is currently available in Level II and IIIA, and is a unique patent-pending construction that uses the aramid fiber, Twaron. Both Level II and IIIA packages meet the NIJ 2005 Interim requirements. The Thin Blue Line also offers the newest carrier design, incorporating CoolTek mesh and Micro Fiber weave.
