All of the gear in this Blowout Bag are contained within a Vanquest FATPack 4X6″ Trauma Pack. We like the FATPack for a number of reasons. One, it can be attached to your kit with either Molle or Velcro. Another, its large grab handle makes deployment quick and easy even with one hand or with gloves. When opened, the stuff is secured in pockets and loops so they won’t dump out on the ground. The FATPack is made of super tough 1000 D Cordura fabric with a water repellent teflon finish. The ripstop nylon interior is also water repellent. The zippers are heavy duty YKK non pinching RC class nylon.
