The Operator was designed from the ground up for plain clothes and undercover work. It is the most covert armor package available.

The system is made of a heavy-weight, moisture wicking and breathable 4-way spandex. On the side of the system is a zipper that does not split the carrier in half. The carrier is pulled over the head and then zipped down, snugging the system up to the body.

12"x16" IIIA Ultralight armor panels cover both the front and back, and are easily removed through zippered pockets for washing when necessary.

    The flexibility of the armor is really impressive. It's not heavy or bulky like I was worried about

    I was skeptical but this one exceeded my expectations. It's incredibly lightweight and flexible. The quality of the material is impressive, and the undershirt is well designed to provide excellent protection without being too obvious. Great investment worth every penny.

    The design is good and discreet, I appreciate that it doesn't draw attention to itself.

    It could use an option for side panels but overall I'm very happy. It was very clear in the description that sides were exposed so I won't drop a point.
