Hello Mr. Rawles,
After perusing the contents listed in survival kits, Bug Out Bags (BOB), and Get Out Of Dodge bags (GOOD), it seems to me that they all have one common glaring omission. That omission is knee pads. It occurred to me recently while fixing a roadside flat that so many survival/TEOTWAWKI tasks require one to get "down and dirty", i. e., working on one's knees. Knee pads can remove a lot of the "pain and suffering" from tasks such as firestarting, fence building/mending, emergency roadside vehicle repair, chainsaw sharpening, and a whole host of other tasks. Not to mention saving wear and tear on those high-dollar Multicam britches.
There are many different brands and types of knee pads, and the range of choices is truly vast. However, for my BOB and vehicles, I went with simple foam pads from Home Depot that are about 1/2 inch thick, cheap, weigh almost nothing, and are far better than nothing at all. - Larrynaz
