kevlar cut vests..pics...

Man I don't know the answer to what they use but why not just call them and ask? In my opinion and no offensce meant just my thoughts but on catch vest as long as all I get through mine is a poke then I am cool w/ that,only a poke but not a long cut. I think some peopple expect a vest to be inpenatrable under all circumstances but every hog is different as well as every dog is different in its size,weight and height as well as how they catch so I guess my point is if there ever is a vest that is 100% unpenatrable then you will sacrifice mobility and heat too much (and even if it was guaranteed unpenatrable I think used enough times the circumstance can arise where even the best may get a poke). I the poke in the pic is from the big hog you recently posted and if it was as rough as you said then your vest really did its job as that looked and sounded like a good,rough hog.The vest you have at this point for me is about what I like on mine,just about right...may get a poke very seldom but wont get the dog ripped.
