I aint going to knock anyones vest just say these are the ones I would and or do run and anything that is just balistic nylon I would stay away from.
X2 Ballistic Nylon is not rated high enough on cut resistance. The cut resistant material goes on the inside. So it may look shredded but what about the dog? A frag jacket even with plates is good for saving your life once. A direct hit will damage Codura or whatever is on the inside. Layers make everything more cut resistant. But pound for pound the Kevlar will give better protection if handled correctly.
