I am not sure what the current thinking on those things is but I thought the point was that Kevlar is acceptable to bureaucrats, not that it is going to stop a bear from tossing your cookies. If you are out in the wild and you will be in deep trouble if a bear takes your food, or wreaks it, that is one issue. But in places like NC the deal is to keep the bears out of the food, if your food is wreaked, you can replace it, or eat scrambled eggs. If you don't want to have to carry armored food containers, that is your choice.
