I have absolutely no negative things to say about this product. I purchased it on a whim just because I wanted a little extra protection without wearing a painfully obvious plate carrier around while traveling or doing general outdoor activities. I’m honestly glad I did because the panel fits the pack perfectly, adds no noticeable weight, and is flexible enough that I don’t notice it’s there at all even though it does help keep the bag somewhat rigid. Absolutely nobody has realized my bag has an armor panel in it.
I had Level II armor in the past and it was SIGNIFICANTLY heavier and thicker than this insert. Overall, it was well worth the investment. Even I forget it’s in there sometimes.
