Feet, hands and eyes.

These are the most used and highly vulnerable body parts in any survival situation.

Get the best fitting and most durable boots available, regardless of cost. Happy feet will keep you upright and moving.

Always have a pair (or two) of high quality glove available and USE them. Cuts on your hands are prime infection routes. In a situation with little to no medical help, you have to do all you can to stay healthy. Check out Youngstown Glove Company waterproof Kevlar gloves.
Protect those eyes above all. Protective glasses are better that nothing but a great pair of goggles are even better (side protection). Ever get whacked in the face when walking through the woods? Or have a strong wind in your face during the winter?

One of the items that Gary included in his Get Home Bag that I rarely see is a mosquito head net. This super lightweight item borders on the necessity/luxury list. It also rates very high on my sanity/mental well-being list, and has the added benefit of helping to break up your silhouette when worn. I cannot express how much I hate mosquitoes buzzing and biting me when trying to sleep.

I also have been moving away from 550 paracord in favor of the 850 paracord. Diameter wise 550 and 850 are practically identical (.125” to .15625” for 550 vs. .15625” to .1875” for 850).
