    I purchased the IIIA 9.5×15 size backpack armor for my Vanquest backpack and it fits fantastic! I really couldn’t believe how light it was when it showed up in the mail! It doesn’t add any weight to my pack at all! Thanks again to everyone at DFNDR, you guys were super helpful! Really great product!

    I saw a field test that demonstrated the effectiveness of DFNDR Armor at a GoRuck Firearms Day event, I purchased a pair of their Level IIIA Handgun rated Backpack Body Armor.

    The backpack armor plate fits perfectly into my GoRuck GR1 laptop pouch and it is 1.3 lbs, you don’t even notice it. The combination of superior craftsmanship and next generation armor is unbeatable. I’ve had my GR1 for 5+ years and is a great piece of gear.

    This review is in reference to the plate designed for the Vertx EDC transit sling. The fit of the plate is very snug, which isn’t a bad thing! The plate is the largest plate you can get into the bag, which is what you want. After installing the plate in the rear zipper pocket of the bag, and my Glock 19 in the concealment area, the bag seemed to stretch a little overnight and now fits everything perfectly. The plate is thin enough and light enough that you’ll forget its there. I love being able to have body armor with me wherever I go, and no one thinks a thing about it! I definitely recommend picking one of these plates up!
