The Trekker I™ Emergency Supply Kit comes with a medium day pack and provides basic survival gear for person to survive for up to three days. This emergency kit is compact enough to store snugly in your car, apartment, and even at the office in the included day pack. Don’t let its compact size fool you—it is loaded with basics and even some extras that lots of kits leave out like water purification tablets, sunscreen, and hygiene items to help you feel more comfortable in a crisis situation. Use alone, as as an add-on to the Trekker II or Trekker IV. See tabs below for more information and contents.
