This is a must have item for trauma first aid kits. Hemostatic agents in bandage or sponge formats like QuikClot or Celox are must haves for first aid kits and blow out kits. The version of QuikClot that THRIVE Life sells is the sponge version, not the powdered version that can cause some problems when it comes time to clean up and suture the wound. Get at least two of these for every first aid or blow out kit. You also should get several compression bandages as these need compression to work.
