CBRN Personal Protective Equipment (PPE) is quite literally the first line of defense a responder or warfighter has against an unknown threat. CBRN threats range in toxicity from acutely lethal CWA or TIC/TIM to carcinogens and incapacitating agents. We purposefully do not list each type of Nitrile or Latex gloves, as those typically come down to personal preference or contractually required suppliers. The boots, suits, gloves, respirators, and vests we list all serve a specific CBRN-driven purpose.
