I have been lugging body armor around for the last 16 years and utilizing it in some very interesting sunny sandy places. Most of what I worry about is 7.62x39 and 19x9 ball ammo; as well as, machete and axe armaments. I not only use the IIIa soft capabilities but I have Frank’s 10x12 UHMWPE III plates front and back in the pockets. This set up weighs about a third of my old vest. Also I wear a 54 long jacket with a 38 inch waist. The XXL fits perfect. Frank and his team really put a great product set together that I rely on!
