One other thing to consider why this may work really well is how much material is in it. One of the latest studies showed that the more agent (Combat Gauze, Celox Gauze, etc) you have the better it works. With the wound packing task trainer I have I am seeing this first hand. If this product has more hemostatic agent in it, it may work better. More agent and more "stuff" filling the void = faster hemostasis. They may have found that combination with an easy way to apply.
