I keep a ESEE COMPREHENSIVE SURVIVAL KIT in my truck which is a awesome kit!!! Very high end gear. I highly recomend it. Its a very compact bag that takes up very little space. Also I keep gloves and hat and water and power bars with me along with a SWAMP RAT Camp Tramp and a Leatherman mutitool and flashlight. My pistol too. In winter months I keep wool socks and winter boots and a heavy coat. Winters here are pretty bad.
